Proposed Technique of Analysis for Absorber/Transmitter Frequency Selective Surfaces

In this paper, we propose a simple technique to analyze absorber/transmitter frequency selective surfaces (FSS). The structure is formed by two FSS, one resistive and conductive. Both FSS are printed on an FR4 dielectric substrate. square loop crossed dipole the geometries considered in paper. combines approaches, equivalent circuit method, scattering matrix method. Two prototypes were built for validation purposes. Simulated measured results good agreement.
