A numerically efficient transmission characteristics analysis of finite planar Frequency-Selective Surfaces embedded in stratified medium

A numerically efficient technique for the evaluation of transmission coefficients of the finite planar Frequency — Selective Surfaces (FSSs) embedded in stratified medium is presented in this letter. The numerical analysis involves the solution of a mixed potential integral equation (MPIE) with the layered media Green's function. The layered media Green's function is derived by using discrete complex image method (DCIM). Numerical results demonstrate the efficiency of the proposed technique for analysis of the planar finite multi-screen FSS embedded in layered medium.
