Electromagnetic Scattering from a Homogeneous Body of Revolution
Abstract
This report considers plane-wave scattering by a homogeneous material body of revolution. The problem is formulated in terms of equivalent electric and magnetic currents over the surface which defines the body. Application of the boundary conditions leads to four simultaneous surface integral equations to be satisfied by the two unknown equivalent currents, electric and magnetic. The set of four equations is reduced to a coupled pair of equations by taking linear combinations of the original four equations. Because many pairs of linear combinations are possible, there are many surface integral equation formulations for the problem. Two formulations commonly encountered in the literature are discussed and solved by the method of moments. A general computer program for material bodies of revolution is developed, listed, and documented. Examples of numerical computations are given for dielectric spheres and a finite dielectric cylinder. The computed results for the sphere are compared to the exact series solution obtained by separation of variables.
