2 2 Product Overview and Structure Absorber is used to reduce overlap and interference of the radio waves due to noise (For EMI solution) or prevent the interference of the antenna (For NFC, RFID) by attenuating the reflection or transmission of electromagnetic waves. Features High permeability and excellent noise attenuation Excellent flexibility and easy to process a shape Improving productivity with a roll type compared with a sheet type How to absorb electromagnetic waves Magnify absorber surface to 500 times [SRA70R series] Magnify absorber section to 500 times [SRA34 series] Absorber can convert the noise into heat energy by using the soft magnetic material. What is a good absorber? The performance of absorber is largely dependent on the material of flaked magnetic powder, layered number per thickness, flatness of the array and so on. Our company is manufacturing the best absorber with differentiated knowhow from the selection of material to production processes.

It can cause problems such as the NFC communication disruption, recognition di stance reduction and so on. But, if you use our absorber between the antenna and metal, it can prevent communication disruption and increase the recognition distance between devices.
