A Study of Electromagnetic Wave Absorber with Broad-Band Frequency Characteristics.
광대역특성을 가지는 전파흡수체의 설계에 관한 연구
Abstract
A wide band design method of an double layerred electromagnetic wave absorber sintered ferrite which has a flat and an anti-grid shape layers is proposed and discussed. The wide band electomagnetic wave absorber can be designed by the equivalent material constants method for the each layer, As a result the wide band ferrite electonmagnetic wave absorber with the band width of 30MHz to 3670, 3680 or 3690MHz were designed under the tolerance limits of -20dB reflectivity.
