Study of electromagnetic wave absorber with wide-bandwidth frequency composed of rubber and ferrite

Electromagnetic wave absorber with widebandwidth frequency composed of rubber and ferrite were prepared by using Mtype hexagonal ferrite. Composition and process and characteristics of absorbing materials were introduced. Reflection coefficient of absorber was measured by using microwave network analyzer from 2GHz to 18GHz. The experiment results show that reflection loss less than -10dB can be obtained in the range 2GHz to 18GHz by combining two kinds of rubberferrite composite.
