Electromagnetic Shielding Material
New Materials EMCscreen（Patent pending）

※High reflectivity of high frequency electromagnetic waves may have a large effect on other devices.

• ・Diffusion of reflected electromagnetic waves：Materials with high reflectivity scatter electromagnetic waves over a wide area, and surrounding equipment may be affected by the reflected electromagnetic waves.
• ・Electromagnetic interference (EMI)：Reflected electromagnetic waves can enter other electronic devices or systems, causing electromagnetic interference and disrupting the normal operation of those devices.
• ・Increasing complexity of the electromagnetic environment：Reflected electromagnetic waves are scattered in multiple directions, complicating the electromagnetic environment and increasing the risk of electromagnetic interference occurring in unexpected places, making it difficult to predict the effects on specific equipment or systems.
• ・Reduced shielding effectiveness：When a material with high reflectivity is used, re-radiation or resonance of electromagnetic waves occurs, the expected shielding effect cannot be obtained, and control of electromagnetic waves becomes difficult.

Example: Malfunction verification test of electromagnetic wave protective clothing (CES protector) for capsule endoscopes

• In developing electromagnetic wave protective clothing for capsule endoscopes, protective clothing was created using MGnet 2-layer (approximately 40 dB) and MGnet 4-layer (approximately 60 dB) materials, and the capsule endoscope antenna was installed in seven locations on various parts of a human dummy. The capsule endoscope was embedded in the abdomen, and the person wearing each protective clothing was irradiated with electromagnetic waves in the frequency band of the telemeter, and the distance at which an error occurred was measured by moving the antenna closer.
• ・MGnet 2-layer (approx. 40 dB)：There was no variation in the distance at which errors occurred depending on the position of the seven antennas. The distance at which errors occurred was reduced almost uniformly.
• ・MGnet 4 layers (approx. 60 dB)：The distance at which errors occurred varied depending on the positions of the seven antennas, and errors occurred even from far away depending on the antenna position.
• For details, please refer to the following documents.
• MGnet Double (approximately 40 dB) and Quadruple (approximately 60 dB) Capsules Comparative test of effects on cell endoscopes

【Features】

• ・It has a shielding performance of 36 to 45 dB from 500 kHz to 1 MHz and 43 to 48 dB from 1 MHz to 6 GHz, and attenuates the electric field strength by about 1/100.
• ・It is less susceptible to reflections and resonances, making it suitable as a solution to prevent electromagnetic interference (EMC) between various devices and electromagnetic waves generated by RF communication waves such as Wi-Fi and 5G.
• ・It is thin and lightweight, can be cut to size, and can be easily attached to parts or walls with an adhesive sheet.
• ・In the unlikely event that the applied area is damaged, it can be repaired by simply applying this material to the damaged area.
• ・It is a fire-retardant material and can be used on the walls of rocket engine rooms.

【Uses: EMC protection against RF communication waves such as Wi-Fi】

• The number of devices that use RF communication waves such as Wi-Fi has increased dramatically, and communication errors and improper operation due to mutual interference between devices is becoming more common.
• ・When performing wireless automatic control in automobile factories, warehouses, etc., by placing it on the wall where electromagnetic waves are expected to penetrate, it is possible to prevent interference with adjacent factory lines and electromagnetic interference from devices such as Wi-Fi.
• ・By placing them on the walls, ceilings, floors, etc. of your office, you can prevent interference between adjacent rooms and electromagnetic interference.
• ・Countermeasures against radiation noise generated by cables and inverters inside various devices such as printers
• ・By attaching it to a vinyl curtain and placing it around the receiver of a medical telemetry system, it prevents interference with neighboring hospitals and electromagnetic interference from devices such as Wi-Fi and LED lighting.

【Use: Countermeasures against cyber terrorism】

• Electromagnetic pulses generated by pulse bombs and high-power microwave weapons generate an electric field strength of approximately 50 kV/m (DC several 10 MHz), inducing high-voltage currents in electronic devices, including information and communication devices, and in power and communication lines. If exposed to an electric field strength of 10 kV/m or more even for a moment, electronic devices and systems are expected to be destroyed.
• ・This material will be applied to the walls, ceilings, and floors of data center rooms to protect servers and various electronic devices.
• ・This material is applied to the walls, ceilings, and floors of rooms to protect the infrastructure for daily life (electricity, gas, water, etc.) and various electronic devices in the communication infrastructure.
