A broadband metamaterial absorber constructed of square metalized segments

The aim of this paper is to study an absorber constructed of square metalized segments arranged on Arlon AD350 foil dielectric. The paper shows that the absorbing metamaterial possesses a broad operational absorption bandwidth of 1.5 GHz to 18 GHz, with an absorption coefficient of 0.9. The absorber also possesses the complete polarization independence at incidence angles ranging from 0$^{\circ}$ to 90$^{\circ}$.
