Abstract

An efficient numerical procedure is developed for analyzing the scattering and radiation characteristics of three-dimensional thin dielectric shells and coated conducting bodies and wires. Senior and Volakis (see Radio Sci., vol.22, p.1261, 1987) extended the single-component sheet model to a double-component sheet model, taking into account the normal electric field in materials. In the present work, their approach is applied in conjunction with the method of moments to solve for various structures which include arbitrary three-dimensional thin dielectric shells and coated conducting bodies and wires. Numerical and analytical bistatic radar cross sections are compared for a specific spherical-shell structure.<>
