Abstract

This work proposes an efficient procedure for evaluating singular integrals arising in the moment method analysis of scattering from bodies of revolution. Perfect electric conductor, dielectric and composite bodies with different electrical sizes and different relative permittivities are analyzed by the CFIE, Muller and PMCHWT integral equation, respectively. It is demonstrated that an efficient singularity removal reduces the number of basis functions necessary to represent the equivalent current distributions
