Analytical and numerical calculation of reflection from a stratified structure backed by a PEMC

Reflection from a stratified medium, backed by a perfect electromagnetic conductor (PEMC) due to an oblique incident plane wave is calculated analytically and numerically. Applying the PEMC boundary condition, the analytic reflection dyad is computed by the notion of propagators and wave-splitting technique and the numerical implementation is carried out using the FDTD method. FDTD modeling is achieved by implementation of PEMC boundary condition in the FDTD technique. Simulation results are provided for verification.
