Abstract

A method of moments (MoM) based on volume-surface integral equation (VSIE) for analyzing electromagnetic scattering of planar composite conductor-dielectric structures is studied. In the dielectric, the prism basis function is used for the tangential electric field and the pulse basis function is used for the normal electrical field to expand the electric flux density in both directions. The conductor surface current is expanded with Rao-Wilton-Glisson (RWG) basis function. In the process of discrete integral equations, the calculation of impedance matrix elements can be implemented through the calculation of impedance matrix elements in the surface integral equation due to the planar characteristics of the structure. Numerical results verify the accuracy of the proposed scheme.
