Abstract: Five volumetric formulations for electromagnetic scattering from dielectric bodies modeled with tetrahedral cells are evaluated to compare their performance. For test problems, all five approaches produce solutions for scattering cross section and internal fields that converge to the correct results. Some formulations are far more efficient than others, however. A point-tested version of the popular Galerkin EFIE-D approach is shown to be similar in far field accuracy to the more expensive Galerkin formulation.
