Electromagnetic wave absorber "MicroSover® (Interference and Resonance Suppression Type)"

It is a near-field suppressive electromagnetic wave absorber (interference/resonance suppression type).

"MicroSover®" is an EMC countermeasure component designed to absorb electromagnetic wave noise generated by information and communication devices, maintaining a clean circuit. When information (current) flows on a circuit board, a magnetic field is generated, leading to resonance and interference noise. By applying a radio wave absorber, it is possible to suppress this interference and resonance. It is used in mobile phones, mobile electronic devices, computers, and gaming consoles. 【Features】 - Flexible: Offers flexibility and ease of handling - Environmentally friendly: Complies with RoHS directives, halogen-free options available - Flame retardant: UL94V-0 certified options available For more details, please contact us or download the catalog.

Electromagnetic wave absorber "MicroSover® (reflection attenuation type)"

It is a distant field resonance-type electromagnetic wave absorber (reflection attenuation type).

"MicroSover®" is an EMC countermeasure component designed to absorb electromagnetic wave noise generated from information and communication devices, maintaining a clean circuit. When radio waves bounce back from a reflective object, applying this absorber reduces the reflection of radio waves at arbitrary frequencies (wavelengths). It is a sheet-type radio wave absorber that can be used for absorbing specific frequencies, from reducing unwanted radiation in small converters to suppressing reflections from structures. 【Features】 ○ Flexible: Easy to handle with flexibility ○ Environmentally friendly: Compliant with RoHS directives ○ Flame retardant: UL94V-0 certified For more details, please contact us or download the catalog.

Tohoku University Technology: Rare earth free electromagnetic wave absorber for 5G: T20-2979

Electromagnetic wave absorber with good noise suppression above 10GHz

With the increase of IoT device and the spread of 5G, noise electromagnetic wave emitted from device integrated transmission circuit has become a serious problem. Since the frequency of these noise electromagnetic wave is around 3GHz, it is required to develop an electromagnetic wave absorber that is efficient in 100-101GHz range. Currently, electromagnetic wave absorber made by mixing flat powder of FeSiAl alloy with resin is in practical use, but the absorption band (resonance frequency) is limited to MHz order.  This invention is about an electromagnetic wave absorber that achieves an absorption from 3 to 12GHz band, with excellent noise suppression above 10GHz, based on the approach of shape magnetic anisotropy improvement. The large shape magnetic anisotropy is achieved by using FeCoCr alloy with a large two phase separation structure. As shown in right figure, electromagnetic wave absorption capacity and transmission attenuation ratio are twice of noise suppression sheet for 5G which is commercially available. Moreover, this electromagnetic wave absorber is useful from economic security viewpoint because it does not contain rare earth element.
