EMCscreen Use Cases
“EMCscreen” is a composite material of aluminum and glass fiber that undergoes a punching process to suppress electromagnetic wave reflection and resonance, effectively reducing electromagnetic interference (EMC) between devices uniformly. It provides stable shielding performance of approximately 45dB for high-frequency waves from 1MHz to over 28GHz. It comes in roll form with adhesive backing, making it easy to apply to components, equipment, walls, floors, ceilings, and more.
*Metal plates or metal film materials provide shielding performance (reflection attenuation) of 100dB or more (over 99.999%), but they may cause unexpected electromagnetic interference due to strong reflections and resonance.
Countermeasure against errors caused by crosstalk between production lines or RFID interference in factories
To prevent crosstalk in factory lines or RFID systems, use EMCscreen on partitions or vinyl curtains placed between lines or devices to block electromagnetic interference.
When installed in areas where electromagnetic interference is expected, it can reduce communication interference by about 1/200, and because it causes minimal reflection or resonance, it ensures stable EMC performance.
Countermeasure against RF communication errors in automotive factories and automated warehouses
In automotive factories or automated warehouses where RF communication controls are used, EMCscreen can prevent interference from adjacent lines or Wi-Fi devices.
When applied to walls where electromagnetic intrusion is expected, it can block external signals by about 1/200, and with low reflection and resonance, it provides stable EMC effectiveness.
Countermeasure against radiated noise from internal cables or inverters in equipment such as printing machines
Radiated noise is widely generated from internal cables or inverters in equipment such as printing machines. These noises increasingly cause electromagnetic interference with circuit boards or data transmission systems. Placing EMCscreen near circuit boards or noise sources helps mitigate these issues. Its thin, adhesive design allows for easy installation and placement.
Countermeasure against server terrorism by EMP bombs or high-power microwave weapons
EMP bombs and high-power microwave weapons generate electromagnetic pulses that produce electric field strengths of approximately 50kV/m (tens of MHz DC). The ground-level intensity depends on the distance from the source and the altitude of the explosion. The higher the altitude, the wider the impact range, but the field strength decreases as follows:
● Short distance (within a few kilometers): several kV/m or more
● Medium distance (tens of kilometers): several hundred V/m to several kV/m
● Long distance (hundreds of kilometers or more): several tens to several hundred V/m
Such electromagnetic waves can induce high-voltage currents in electronic devices and power/communication lines. Even a brief exposure to more than 10kV/m can destroy electronic systems.
According to IEC 61000-4-3 electromagnetic compatibility standards for commercial electronics, resistance to around 10 V/m is required. However, in reality, even a few hundred V/m to 1kV/m can disrupt operation, cause noise, and lead to data or communication errors.
To protect servers in data centers and electronic equipment in essential infrastructure (electricity, gas, water, etc.) and communication systems, it is necessary to reduce the field strength from 10kV/m to below 10V/m. This requires a shielding performance of at least 60dB.
Ordinary reinforced concrete buildings with a thickness of 10cm offer 20–30dB of shielding. EMCscreen provides 45–50dB, resulting in a combined shielding of 65–80dB when applied to walls, ceilings, and floors. This reduces electric field strength by about 1/1800 to 1/10000, lowering 10kV/m to less than 5.6V/m.
Such shielding performance is also effective against data leakage from TEMPEST attacks.
Critical infrastructure operators such as power and telecom providers, as well as defense and disaster response agencies, are mandated by the Cabinet Office to take countermeasures. To protect vital electronic equipment, storing them in shielded rooms built with EMCscreen during high-risk periods—such as EMP threats or solar flares—can prevent damage.
