Abstract

This paper presents an integral equation formulation for electromagnetic scat- tering by inhomogeneous infinite cylinders having arbitrary scalar permittivities and per- meabilities. The formulation involves both volume and surface integrals with only one unknown field component, and is applicable to both transverse electric and transverse magnetic cases. This volume-surface integral equation is well-suited for numerical imple- mentation. In this paper, the integral equation is first derived by integrating the wave equation with the aid of the free-space Green’s function, and then analyzed from the physical point of view, resulting in a new interpretation for the scattering mechanism. Finally, the equation is programmed using the method of moments with pulse expansion functions and point-matching. Numerical results are shown to demonstrate the validity of the formulation and the new interpretation of the scattering mechanism.
