The application of absorbing materials in RFID is described

With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing day by day. In the airport, flights cannot take off due to electromagnetic interference, and in hospitals, mobile phones often interfere with the normal work of various electronic diagnosis and treatment instruments. Absorbing material is a kind of composite material with excellent absorbing ability to electromagnetic wave. This kind of absorbing material is a kind of magnetic alloy with high permeability formed by physical refinement and magnetic field treatment, and evenly dispersed in polymer.

The principle of microwave absorbing material is based on magnetic microwave absorber, which converts electromagnetic wave emitted by electronic equipment into heat energy by means of insulation loss, magnetic loss and impedance loss to reduce electromagnetic radiation. It has the characteristics of high permeability and wide optional frequency band, and can be developed for specific frequency band.

the absorbing material has good absorption characteristics in the range of 10MHz ~ 6GHz, which can avoid electromagnetic interference or leakage caused by secondary reflection. The products are mainly microwave absorbing patch type, and can be processed into various shapes according to customer requirements. The absorbing plate can be used in the electronic equipment cavity of notebook computer, mobile phone, communication cabinet, etc. The absorbing material has good absorbing effect on electromagnetic wave and wide absorption frequency. It can be customized according to the frequency band required by customers. It has thin thickness, high cost performance and wide application range.

With the increasingly strict international standards for electromagnetic interference control, China has also been in line with the international standards, speeding up the control of electromagnetic noise, especially electronic products. Therefore, it has become a major subject of material science to control electromagnetic pollution and find a material which can resist and weaken electromagnetic radiation.
