A High Order Numerical Investigation of Electromagnetic Scattering From a Torus and a Circular Loop

The normally integrated magnetic field integral equation (NIMFIE) formulation is used to generate accurate numerical results for toroidal scatterers. Numerical data for the surface currents and scattering cross section induced by a plane wave on a perfectly conducting torus are presented. The special case of a thin circular loop is also examined. These results are expected to find use in numerical validation.
