Abstract

This work proposes an efficient procedure for evaluating singular integrals arising in the moment method analysis of scattering by bodies of revolution. Perfect electric conductor, dielectric, and composite bodies, varying in size and relative permittivity, are analyzed by the CFIE, Müller, and PMCHWT formulations, respectively. The integrand singularities are extracted and calculated in closed form and numerical integration is applied only for regular functions. It is shown that an efficient singularity removal considerably reduces the number of basis functions required to represent the equivalent current distributions
