Ultrathin Broadband Absorber Using Frequency-Selective Surface and Frequency-Dispersive Magnetic Materials

Abstract

The bandwidth of frequency-selective surface (FSS)-based absorber decreases when high permittivity material is used to reduce the thickness of the absorber. A solution of this thickness-bandwidth dilemma was presented by using resistive FSS layer and frequency-dispersive magnetic material (FDMM) in substrate. The FDMM was designed for a certain profile of… (More)
