Electromagnetic wave absorber with wide-band frequency characteristics using exponentially tapered ferrite

테이퍼부를 가지는 초광대역 페라이트 전파흡수체

A wide band design method of an electromagnetic wave absorber with using exponentially tapered ferritic is proposed and discussed. A theoretical model using the equivalent material constants method is also proposed to analyze the regions varying sptially in the shape of ferrite. Based on the developed model, wide band electromagnetic wave absorbers with excellent reflectivity frequency charaateristics in the freqency rang eof 30MHz to 2,150MHz or 2,430MHz were designed.
