CompanyName ProductName Duesseldorf, Germany ALPS Electric has developed the HMLSR Series of Liqualloy magnetic sheets for radio frequency identification (RFID) applications. The magnetic sheets utilize ALPS’ Liqualloy metallic glass powder to boost the sensitivity of RFID antennas. The product enhances electromagnetic compatibility (EMC), eliminating the problem of interference with waves that should reach the wireless tag from radio or electromagnetic waves generated by nearby parts and devices. The amorphous structure of Liqualloy allows a high degree of freedom in the shaping process, and it displays soft magnetic properties that can be readily activated by exposure to magnetic fields. In addition, its high permeability is 1.3 times greater than that of Fe-Al-Si alloys, the leading magnetic material, giving it superior capacity to absorb radio and electromagnetic waves. In RFID technology, it is not unusual to install parts and devices on the back of wireless tag antennas, eventually causing interference with waves that should reach the antenna. The Liqualloy magnetic sheets effectively focus waves to the antenna, increasing RFID antenna sensitivity. Alps Electric Europa GmbH , Duesseldorf, Germany. www.alps-europe.com.
