Abstract :
In this paper, several integral equations derived for scattering problems are evaluated by the MoM technique and compared to each other in the numerical analysis of scattering by bodies of revolution when illuminated by plane-waves. The numerical results are compared to Mie-series analytical solutions. Dielectric and composite bodies with different electrical size and different relative permittivity (for dielectrics) are analyzed. It is shown that Muller integral equation is the most accurate solution for dielectric and layered bodies analysis, PMCHWT is the most accurate for bodies with homogeneous regions analysis
