As one of the effective means to restrain EM interference and realize EM protection, EM shielding means to limit the transmission of EM energy from one side of the material to the other side [37,38]. The mechanisms of EM shielding can be analyzed by transmission line method. Materials with high conductivity are usually used to restrain EM radiation, with the reflection effect of conductor on EM waves. Shielding effectiveness (SE) is usually used to represent the shielding ability and effect of materials on EM [39,40].

Although traditional metals and alloy materials have a good EM shielding effect, their development is limited by the disadvantages of heavy weight, high cost and poor corrosion resistance. Novel EM shielding materials with lightweight characteristics are becoming more and more popular. EM shielding fabrics have the advantages of low density, good flexibility and light weight, which are widely used in the manufacture of EM protection products such as protective clothing, shielding tents and shielding gun-suit [41]. EM shielding fabrics also have strong one-time molding ability, excellent designability, breathable fabrics properties, both soft and EM shielding properties, which can be made into different geometry to shield radiation source, but also can be processed into shielding suit and shielding cap to make the staff from EM radiation [42]. In addition, metal fibers fabrics also have other functions, such as antistatic, antibacterial and deodorant. EM shielding fabrics are the ideal shielding materials with outstanding properties. The research of EM shielding fabrics can be divided into theoretical calculation and experimental measurement.
The expression to measure shielding effect of materials are transmission coefficient T and Shielding Effectiveness (SE). The transmission coefficient T is the ratio of electric field intensity Et (or magnetic field intensity Ht) at a place with a shield to electric field intensity E0 (or magnetic field intensity H0) at the same place without a shield and the formula is as follows,
T=EtE0=HtH0 (1)SE refers to the shielding capability and effect of a shielding body against EM interference, which is often expressed logarithmically, as defined below [37],
SE=20lg(E0Et)=20lg(H0Ht)=10lg(P0Pt)=20lg1|T| (2)where lg=log10; P0 is the power density without shielding; Pt is the power density with shielding body at the same place. For the convenience of calculation, the most used formula is SE=20lg(E0Et).
According to Figure 3, SE can be composed of reflection loss SER, absorption loss SEA and multiple reflection loss SEM.
SE=SER+SEA+SEM (3)The current theoretical calculation methods of EM shielding fabrics are to directly equivalent the conductive yarns with shielding performance to metal plates, and then the equivalent calculation is carried out according to the fabric structures corresponding to metal plate structures, such as no pore, pore structure, metal grid, layered parallel array and other structures, so as to calculate SE of fabrics. Based on transmission line theory, there are three different mechanisms for EM waves attenuation by the shielding body: reflection attenuation, absorption attenuation and multiple reflection attenuation. Firstly, metal plates are classified into no pore, pore structure, metal grid, layered parallel array (as shown in Figure 4), then the theoretical formulas or semi-empirical formulas of EM shielding are derived based on transmission line theory and equivalent circuit methods [43,44,45,46].
Schematic diagram of parallel array structures of metal.
According to the literature [47,48], under the condition of far-field plane waves, transmission coefficient of no pore metal plates is as follows,
(T=4ηeηme&#;γd(ηe+ηm)2/[1&#;(ηm&#;ηeηm+ηe)2&#;e&#;2γd]ηm=3.69×10&#;7fμrσrηe=377Ωγ=(1+j)πμfσ (4)where ηe is the impedance of EM wave; ηm is the impedance of the metal plate; γ is the propagation constant of EM wave in metal; d is metal plate thickness; μr and σr are relative permeability and relative conductivity of metal plate; μ and σ are permeability and conductivity of metal plate. Combined with Equation (2), the SE of metal plate without poles can be obtained.
As for pore structure metal plates, the transmission coefficient of pores Th can be obtained according to the literature [49],
Th=4n(qF)3/2. (Circular pore) (5) Th=4n(kq&#;F)3/2. (Rectangular pore) (6)where q is the area of a single circular pore; q&#; is the area of a single rectangular pore; n is the number of holes; F is the metal plate area; k=baξ23, a and b are short and long sides of rectangle pore, respectively; when the rectangle is square, ξ=1; when ba&#;5, ξ=b2aln0.63ba. The transmission coefficient of pore structure metal plate is Th=T+Th. Combined with Equation (2), SE of metal plate with pole structure can be obtained.
Henn et al. [50] first proposed that metallized fabrics were regarded as pores structure metal plates, and deduced the SE formulas of metallized fabrics by calculating the value of pores structure metal plates SE. Safarova et al. [51] used the above method to calculate metal fibers blended fabrics, analyzed the fabrics pore shape with image processing technology, approximated the irregular shape into a rectangle, and established the SE model about fabrics porosity, thickness and fibers volume.
The method of equivalent metal yarns to pores structure metal plates provides an idea for solving the SE of EM shielding fabrics. However, these models have certain limitations, requiring that the whole fabric has good electrical connectivity, resistance must equal to that of metal plates, fabrics must have a certain thickness, and the pores in fabrics need to be regular. In addition, simply approximating the shape of a single pore to a rectangle or a circle will cause a large error. When metal fibers content is too low, these models are not applicable, which is not conducive to the development of EM shielding fabrics.
SE formulas of metal mesh can be obtained from Literature [52].
SE=Aa+Ra+Ba+K1+K2+K3 (7)where Aa is absorption loss of pores; Ra is reflection loss of pores; Ba is multiple reflection loss; K1 is the modification item related to the unit area and the number of pores K2 is the modification item related to skin depth; K3 is the modification item for coupling of adjacent pores. The calculation formula of each item was shown in Table 1, and the data was derived from [52].

&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; Open in a new tabIt is difficult to accurately calculate the SE of metal grids. For the convenience of calculation, under approximate conditions, the SE of metal materials with good electrical conductivity mainly comes from reflection loss, and the absorption loss can be ignored. Engineering calculation of SE can be obtained that [53],
SE=20lg1s[0.265×10&#;2Rf]2+[0.265×10&#;2Xf+0.333×10&#;8f(lnsa&#;1.5)]2 (8)where s is the pitch of the metal grid; Rf is AC resistance per unit length of metal grid; a is metal fibers radius; Xf is the reactance per unit length of the metal grid.
Chen et al. [54] made polypropylene fibers woven with copper wire and stainless-steel wire conduct fabrics, respectively, proposed the metal grid structure, and calculated conduct fabrics SE by using the formulas of metal grid structure from the literature. In the frequencies range of 30 MHz&#;1.5 GHz, the measured values were quite different from theoretical values, which may be caused by poor contact or low conductivity of fabrics at yarn intersections. Cai et al. [55] used a metal grid structure model to calculate the SE of stainless-steel fibers blended fabrics. When the content of stainless-steel fibers was 5%, 10% and 15%, respectively, the calculated results were close to experimental results under low frequencies conditions. Rybicki et al. [56] established an equivalent circuit model of conductive grid yarns based on a periodic metal grid structure, believing that SE depends on grid size, thickness and resistivity of grid material. Compared with simulation experiments, this method had certain feasibility.
Although the structure of metal mesh is close to real 2D fabrics in shape, the method requires that the intersecting points of fabrics grid should be conductive, the pores should be regular, and the content of conductive fibers should not be too low. Moreover, the yarns containing metal fibers are a mixture of metal fibers and other fibers, which will affect its EM parameters and cause large errors. This method is not suitable for the large degree of buckling or 3D fabrics, which will limit the development of EM shielding fabrics structure to a certain extent.
Other optimization methods to calculate SE include Sabrio&#;s metal parallel array method, as shown in Figure 4 [57]. The metal grid was divided into two periodic arrays of parallel metal plates with different angles, and SE of each periodic array metal plate can be calculated. Liang et al. [58] derived a SE model of 2D metal fibers blended woven fabrics base on this method. According to the comparison between theoretical values and measured values, yarn diameter, electrical conductivity and weaving Angle all have a certain influence on SE. Whether the fabric is conductive at the yarn crossing point has no effect on this model, which has high applicability.
Yin et al. [59] established the SE model of plain weave fabrics by the way of the weighted average based on fabrics buckling surface equation and fabrics structure. This model explained the mathematical relationship between SE and the parameters of plain weave fabrics such as pitch, thickness and fiber volume content. The trend of this model was basically consistent with the experiment, which provided a theoretical reference for the effective design of EM shielding fabrics with a large degree of buckling.
The metal yarn was equivalent to the structure of no pores, pores, metal grid and so on, requiring yarn crossing point conductive, and fabrics need to have a certain thickness, which will limit fabrics design and development to a certain extent and there will be considerable limitations. The method equivalent to parallel metal array structure was more accurate and had no effect on whether the yarn crossing point was conductive or not, but this model was not suitable for 2D fabrics with a large degree of buckling and 3D fabrics. At present, the research on SE are limited to 2D fabrics, and there are few reports on 3D fabrics. 3D fabrics have greater development potential and stronger functions than 2D fabrics. The study of the influence of fabrics structure on SE will be the theoretical guiding significance to the development of 3D EM shielding fabrics.

Using products made from EMF shielding materials is a way around this. Such products allow you to enjoy the modern world&#;s progress, but more safely.
There are thousands of peer-reviewed scientific studies confirming that long term exposure to EMF is a severe health hazard. The WHO (World Health Organization) also classifies EMF as a Class 2B carcinogen.

In , Benjamin Franklin performed an experiment to better understand electricity, in which he lowered an uncharged cork ball through an opening of an electrically charged metal can, using a silk thread.
In , Benjamin Franklin performed an experiment (no, not the more famous one with the key) to better understand electricity. | Image Source: ArtHistory.CoCork is a &#;dielectric&#; material (like we use in our SYB H.A.R.D. anti-radiation adapter), and it is attracted to electrically charged materials.
Franklin&#;s hypothesis was when he lowered the cork ball into the can, it would drift towards the side of the can. The result of this experiment was completely different, as the cork ball showed no such behavior. The cork was not attracted to the can.
He then took the cork ball out, lowered it near the exterior of the same can, and the ball was attracted to the can.
Despite several attempts, Franklin never managed to understand this phenomenon.
Eighty-one years later, an English scientist, Michael Faraday, performed a similar experiment to that of Franklin&#;s.
He built a room coated with metal foil and allowed a high-voltage electric current to strike the outer walls. He used an electroscope to detect the level of electricity inside the room.
An electroscope is a scientific instrument used to detect the presence of an electric charge.
Surprisingly enough, the electroscope detected no trace of electricity inside the room. This allowed Faraday to conclude that conductive materials are capable of shielding electric and magnetic energy.
That discovery was key, and the instrument that he created from his findings is now known as a Faraday Cage.
Example of a Faraday cage actively blocking electricity. | CC BY-SA 3.0After his theory was published, people all over the world began applying his approach to different inventions. The scientific principle of the Faraday Cage is used to this day. From guarding sensitive military equipment to protecting Airplanes from lightning strikes, the applications of the Faraday Cage are vast.
To understand how EMF shielding works, we need to understand the mechanics of electricity.
Everything in the universe is made from atoms. And atoms themselves are made from smaller subatomic particles.
The center of an atom is called a nucleus, which contains subatomic particles like protons, electrons, and neutrons. Protons and neutrons stick together with the nucleus, but electrons spin around the nucleus in different layers called electron shells.
Electrons usually remain at a distance from the atom&#;s nucleus in their shells.
The shell closest to the nucleus can hold two electrons. The next shell can hold up to eight. The outer shells can hold even more. Some atoms with many protons can have as many as seven shells with electrons in them.
The electrons in the shells closest to the nucleus have a strong force of attraction to the protons. Sometimes, the electrons in an atom&#;s outermost shells do not have a strong force of attraction to the protons. These electrons can be pushed out of their orbits.
Applying a force can make them shift from one atom to another. These shifting electrons are electricity.
Now, when the electricity flows, it generates a magnetic field. This combination of electricity and magnetism is called electromagnetism. And the magnetic field created by the flow of electricity is called an electromagnetic field, or EMF.
When EMF gets in contact with the EMF shielding material (conductive materials), the charge present in EMF shielding material gets disturbed. When this happens, the conductive material either cancels out the charge, or absorbs the charge and adjusts it within itself.
Due to this, EMF stays outside, and the inner side of the material stays EMF-free.
In simple words &#; you can think of EMF shielding materials as a window shade. Except instead of blocking sunlight, they deflect EMF radiation.
The company is the world’s best Whoelsale EMF Protection Canopy Company supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
A question I get asked frequently is, what happens to the EMF waves after they&#;re deflected? Do they bounce off into a more concentrated or targeted beam of radiation that hits the person next to you?
This is a perfectly valid question. Naturally, if you&#;re sending harmful waves of radiation away from your own body, you want to be sure those waves aren&#;t doing extra damage to someone else.
The answer here is quite simple: When you use EMF shielding products like mine to deflect radiation, the radiation does bounce in the opposite direction. However, it does not become more powerful.
In fact, quite the contrary. The rays are deflected away and gradually dissipate, because the power"Power" in a scientific context refers to the rate at which work is done or energy is transferred. In simpler terms, it's how fast something is using energy. For example,... More of EMF radiation diminishes exponentially with distance. I explain a bit more about that in this post.
Now, this post discusses EMF shielding materials. There are other types of products that purport to provide EMF protection: neutralizers, harmonizers, and certain types of crystals like orgonite.
As I&#;ve just described, EMF shielding materials work by blocking and deflecting EMF radiation. And because of this, it is possible to measure the claims of EMF shielding products like the ones I make and sell.
So we have testing performed at independent laboratories to demonstrate the shielding power of my products.
But what&#;s even better is, you don&#;t need to take my word for it. Because you can actually measure the efficacy of my products for yourself, using tools that you can buy online. And I have a collection of resources designed to help you do just that.

It&#;s just that certain metals are commonly used due to their high conductivity.
Since most electronic gadgets emit EMF on the radiofrequency range of the electromagnetic spectrumThe electromagnetic spectrum encompasses the entire range of electromagnetic radiation, which varies in wavelength and frequency. This spectrum includes, in order of increasing frequency and decreasing wavelength, radio waves, microwaves,... More, scientists have selected a few metals that can be used as powerful RF-blocking materials.
This list of highly conductive metals includes silver, copper, aluminum, gold, and steel.
Silver: In terms of EMF conductivity, silver holds the highest position. If you&#;ve purchased scientifically proven EMF shielding products before, you may have noticed that many of them contain a significant portion of silver.
Here at SYB, we use silver as the shielding material in all of our apparel products because, in addition to being effective at deflecting electromagnetic radiationElectromagnetic radiation refers to the waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes a wide range of electromagnetic waves, from very long radio waves... More, silver is also antibacterial and antimicrobial.
Copper: Among all non-precious metals, copper has the highest conductivity.
Aluminum: While not as effective as copper or silver, aluminum, too, provides powerful EMF shielding.
Gold: Gold is also highly conductive. But, due to its expensive nature, gold is used less frequently in EMF shielding materials.
Steel: Steel has low EMF conductivity compared to aluminum, silver, and copper but higher than tin, titanium, and stainless steel.
You may have seen many people using Aluminum foil to block EMF. In fact, one person from the UK lined his room with thin layers of tin foil and spent close to £1,000 (about $1,300) to do it. Why? In hopes that it would block EMF from reaching his room and ease his electromagnetic hypersensitivity symptoms.
So, does aluminum foil really block EMF?
Yes. While it&#;s not as powerful as silver or copper, it does provide adequate EMF protection while also being very cost-effective.
The only downside of using homemade aluminum foil EMF protection is that you have to be very careful about how you use it. In fact, this goes for all metals used to shield EMF. A simple mistake in your EMF shielding efforts can cause them not work or, worse, reverse the effects.
On top of that, aluminum foil is super fragile. So, it takes little to no effort for it to tear and disengage your EMF shielding.
This is why we recommend going for EMF shielding products like the ones SYB manufactures instead.
There are tons of magnet-based products on the internet claiming to protect you from EMF radiation. But do they actually work?
Most magnet-based EMF-shielding products claim that they use a process called entrainment to capture radiation emissions from your device and harmonize them in a way that cancels their effects.
So, does science actually back up this process, or is it just hokum?
Well, these companies do cite a study from the journal Stem Cell Research that states endogenous or internal EMF frequencies act on a molecular level yet can be entrained through harmonic resonance to follow exogenous (external) frequencies.
And if we go by this study, one can theoretically create a product that entrains and harmonizes radiation in a certain way. But there are two problems with this.
So, do magnet-based EMF shielding products block EMF radiation?
Well, I can&#;t confirm or deny this. However, if you&#;re already using such products and feeling a difference, then, by all means, keep using them. But if not, I recommend sticking to proven, research-backed EMF shielding products. Ones that you can even test at home to see their effectiveness.
The human body has its limitations on how much EMF exposure it can tolerate. Before human-made EMF came into the picture, our body was perfectly capable of handling the amount of EMF present on Earth.
But that is not the case anymore. With the increasing development in EMF emitting technology, we&#;ve reached a point where it&#;s simply too much for the human body.
This excess amount of EMF exposure can lead to a number of health issues in your body. Even if your body can fight the effects now, eventually you will start to see symptoms of EMF-induced health issues.
These EMF-induced health effects can be avoided or minimized by merely reducing your EMF exposure.
Let&#;s look at some everyday gadgets that highly contribute to your EMF exposure and EMF shielding products that you can use to make them safer.
There is no debate about whether carrying and using a cell is harmful. As much convenience as these devices provide, EMF emitted by cell phones can cause serious harm to your health.
Statistics say that more than half of cell users carry their phones either in their pocket or bra.
This exposes users to a massive amount of EMF, as cell phones continually communicate with the network tower &#; using EMF.
When you keep your this close, the radiation emitted by your has to go through your body to find a network. And since your body is a good absorbent of EMF, it stays and damages your cells and tissues.
Now, if we say don&#;t carry your in your pocket, most people will ignore it. After all, it&#;s very convenient to carry cell phones in pockets, which makes it easier for us to ignore the health risks.
That&#;s why we make the SYB Pouch: a simple and affordable cell radiation protection sleeve. It&#;s a great alternative to expensive EMF blocking cases and covers.
SYB&#;s 5G Shield is easily slipped between you and your .The Pouch puts a layer of EMF shielding material in between your and your body. This means the can stay on and emitting EMF (if all EMF was blocked, your simply wouldn&#;t work), but the harmful radiation gets deflected away from your body.
Similarly, we have the SYB 5G Shield. This product serves the same functions but is designed to be used differently, so you can choose what is more convenient for you.
Health experts strongly recommend against using a laptop on the lap.
There are two reasons behind this. The number one reason is that laptops, similar to cell phones, emit a massive amount of EMF radiation. The second reason is that laptops generate heat. In fact, they generate so much heat, it can damage your skin.
But many of us disregard this health hazard, because it&#;s just so convenient to use a laptop on your lap.
And that&#;s why we make the SYB Laptop Pad. Our SYB Laptop Pad is designed using a mesh of ferromagnetic steel and aluminum plates. You can place the laptop pad on your lap and your laptop on the pad.
This protects your lower body from the EMF emitted by the laptop, and also reduces the heat.
The Laptop Pad is portable, comfortable, and easy to clean.
Health bodies globally recommend against using BluetoothFrom the perspective of someone concerned about the health effects of electromagnetic radiation, understanding Bluetooth radiation is crucial, especially in our increasingly wireless world. Bluetooth technology, ubiquitous in our daily... More headsets, as placing an EMF source so close to your brain is dangerous.
Bluetooth headsets, unlike wired headsets, are an EMF source. So, when you wear them, large amounts of EMF get absorbed by your brain.
So, try to avoid using Bluetooth headsets as much as you can.
And although there are products like AirPod emf blocker stickers in the market that claim to reduce your EMF exposure from your AirPod or other Bluetooth headsets, we don&#;t recommend using them.
So far, there&#;s no scientific explanation of how these stickers work and absolutely no concrete proof of them actually working.
I suggest going back to the basics and creating a distance between your body and the EMF source. And wired headsets can help you with that.
When you use wired headsets, you keep the actual EMF source (e.g., the ) away from your head, greatly reducing your EMF exposure.
I say &#;reducing&#; because, although wired headsets are safer than Bluetooth ones, they&#;re not completely EMF-free. This is because EMF from your device still travels up through the wires and directly into your ears, and through to your brain.
The SYB H.A.R.D can be used with any headphones or headset.We solve this with our SYB Air Tube Headset and SYB H.A.R.D.
In the SYB Air Tube Headset, the wire stops part-way up the cord (a safe distance from the head), and hollow flexible tubes take over. This stops the radiation from your cell from being conducted up to your head and into your brain.
And if you want to use your premium headset, you can go with the SYB H.A.R.D. This product stops EMF from your right at the starting point and only lets clean audio pass through the wire.
WiFi routers are one of the most common electronic devices present in the average American home. Routers are powerful EMF generators, and exposing yourself to those emissions for a more extended period can be hazardous.
We recommend using a wired internet connection. Yet, we also understand that this may not be an option for many people.
Turning your WiFi off when you sleep will also help to limit your exposure.
For times when you do need to have the WiFi switched on in your home, we have solutions like the SYB Picture Frame.
This is a powerful EMF shield that you can place in front of your WiFi router, facing the area where you spend the most time.

The EMF pollution in our environment is ever-growing. And although blocking EMFs from your gadgets helps a lot, it&#;s sometimes not enough.
EMF-blocking fabric adds a new layer to your EMF protection efforts.
EMF-blocking fabrics are a mix of materials like copper, aluminum, silver, stainless steel, and nickel with natural or synthetic fibers like cotton, rayon, silk, or polyester. They&#;re used to produce radiation protection clothing that looks and feels like regular clothing but with an added layer of protection.
This unique blend of metal and fiber creates a fabric that turns these clothes into powerful EMF shields. The garments stop electromagnetic radiation from entering the body by deflecting it in the opposite direction.
Shielding solutions like pouches and laptop pads are effective for most people, but sometimes they&#;re not enough. This is especially true if any of these factors apply to you:
If one of these is true for you, shielding EMF sources inside your house may not be enough.
In this case, you can resort to a whole house/room shielding solution using EMF shielding paint, also known as 5G"5G" refers to the fifth generation of wireless communication technology, a step up from the previous 4G, 3G, and 2G networks. It's designed to provide faster internet speeds, more reliable... More protection paint.
EMF shielding paints are created using highly conductive materials that can block extremely low frequencyDefinition and Characteristics Extremely Low Frequency (ELF) refers to the lower end of the electromagnetic (EM) spectrum with frequencies from 3 Hz to 300 Hz. This range lies below the... More (ELF) radiation from electrical outlets to higher-frequency EMFs like those used by cell phones and WiFi routers.
With EMF shielding paint, you can turn your house/room into something close to a Faraday Cage.
If you plan to use EMF shielding paint, we recommend engaging the services of an expert. This is because whole-home or whole-room shielding solutions are complex and easy to get wrong.
Building Biology Institute is one of the places where you can find certified EMF experts.
You must know that when you use an EMF shielding product, you are not canceling the EMF. You are just stopping it from entering your body by diverting it in the opposite direction.
If you try to block 100% of the EMF, your wireless gadgets will not function.
Let&#;s take the SYB 5G shield as an example. It&#;s a powerful EMF shield with a -case-like structure.
You place the 5G Shield between your body and your while carrying it in your pocket. When you do this, the Shield will deflect all the EMF radiation away from your body.
Always remember that you should never keep an electronic gadget between an EMF shielding material and your body.
For example, you should never pick up the and place it against your head with the 5G Shield on the back of your . If you do this, all EMF will be directed towards your face.
All science-based EMF shielding products are made using this logic.
Another thing is, you should never cover your electronic gadgets with EMF shielding products.
These gadgets are designed to connect you to the network, even in adverse conditions. So, when a device is in a low network area, it will respond by emitting even higher amounts of EMF in order to stay connected and give you service.
Covering your device will cause the same phenomenon as using your in an elevator. This is the reason our products like our SYB 5G Shield, SYB Pouch, and SYB Laptop Pad, are designed to shield from one side only.
This way, your device will be able to function as normal, even as you stay protected from radiation. And most importantly, it will not emit any more EMF than it has to.
I hope this post has helped you to better understand how EMF shielding works and how it can protect the health of you and your family. To learn more about our lab-tested EMF protection products, start here.
