Analysis and design of a Salisbury screen absorber with High Impedance Ground Plane

Abstract

In this paper, thin and broadband absorber of two layers consisting of high impedance ground plane (HIGP) is introduced. By controlling the phase characteristics and the resonant frequency of the HIGP, the performance of the Salisbury screen absorber can be enhanced. The equivalent circuit model is then used for results prediction and explanation of the working principles of the thin and the wideband absorbing structure.
