Abstract

An ultra-wideband and polarization-insensitive microwave absorber, which is composed of three layers of metasurfaces with different patterns and sheet resistances, is proposed in this paper. The bandwidth of effective absorptivity (over 90%) is from 6 GHz to 50 GHz, with relative absorption bandwidth of 157%. The equivalent circuit of the proposed absorber is investigated thoroughly. The circuit model analysis results agree quite well with the numerical simulation, which indicates the accuracy of the equivalent circuit model. The performances of this absorber under various polarizations and incident angles are also investigated. The results indicate the proposed absorber is polarization insensitive and has relatively good stability of wide incident angles.
