Hybrid MPIE Method with Anisotropic Impedance Boundary Conditions for Layered Media

A mixed potential integral equation (MPIE) method combined with anisotropic impedance boundary conditions is proposed for the analysis of scattering from layered media. In this method, anisotropic surface conductivity is modeled by the impedance boundary conditions. As a result, only these surfaces need to be discretized. Numerical example is demonstrated to show the accuracy of this method.
