Abstract

In this paper, the problem of electromagnetic scattering by a conducting body of revolution is solved using the finite‐difference technique in frequency domain. Two coupled partial differential equations, derived based on the coupled azimuthal potentials introduced by Morgan, Chang, and Mei are solved over a domain surrounding the scatterer. Boundary‐fitted curvilinear coordinates, which avoid the problem of staircasing, are used to discretize the domain of computation. Results are presented to demonstrate the accuracy of the method.
