Ferrite-Iron-Rubber 복합체의 전파흡수특성
The Microwave Absorbing Characteristics of Ferrite-Iron-Rubber Composites.
초록
복합 Ferrite 전파흡수체의 성능은 두께가 얇으며 대역폭이 넓을수록 우수하다. 본 연구에서는 복합 Ferrite 전파흡수체의 정합두께를 감소시키기 위하여 Ferrite-Iron-Rubber 복합체를 제조하고 그 특성을 고찰하였다.
Wide-band absorbency and small layer thickness are required in the high- performance microwave absorber. In order to reduce the thickness of the absorber, ferrite-iron-rubber composites were proposed and its properties were investigated. The increase in both real part of perrreability and permittivity of the composites were observed with addition of -Fe powder and this behavior results in the decrease of fm dm term. The matching thicknesses of ferrite-iron-ruber composites were relatively small(0.5~2.0 mm) in the frequency range of 3~17 GHz as comIBfed to than that of ferrite-rubbr composit.
