**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.
