Electromagnetic propagation characteristics in K-layered dissipative media with rough surface

In this paper, a novel method for the electromagnetic field in non-planar layered dissipative medium based on Poggio-Miller-Chang-Harrington-Wu-Tsai (PMCHWT) integral equation is presented. Triangular patch basis functions are employed to mesh the media interfaces. We use Rao-Wilton-Glisson (RWG) basis functions to approximate the unknown coefficients of equivalent electric and magnetic surface currents on the media interfaces. The Galerkin's method is introduced to transform the continuous surface integral equation (SIE) to a linear matrix equation. Numerical results of embedded spheres structure are presented to validate the proposed method.
