Flexible Absorbent Material

(FAM)

 

    

FAM is a thin and flexible material, include soft rubber type and flexible sintered ferrite sheet with higher permeability. It can be cut any shape easily, freely arranged in space and provide effective EMI suppression in a wide frequency range (1MHz to 18GHz). Also can be a solution for RFID (Radio Frequency Identification) system on metal. It suitable for LF(125/134.2KHz) and HF(13.56MHz) bands on metal environment. It also works well in NFC (Near Field Communication)  technology application and Wireless Charger (WPC/Qi).

Effect Diagram - Magnetic Shield :

FAM can change the magnetic flux path to avoid the magnetic flux affect others components.

 

 

 

Effect Diagram - RFID/NFC on metal :

The magnetic flux induced eddy current and generated a reverse magnetic field to offset the magnetic flux to cancel the communication. After  attached FAM between metal and RFID antenna, the communication will recover.

 

 

  

Effect Diagram - Wireless Power Charger :

FAM can be used for wireless power charger to avoid eddy current when RX coil attached on metal and change the magnetic flux path between TX coil, RX coil, magnet.
