Internal field pulse diffraction by an ice sphere

A normalized Poynting vector impulse response approximation evaluated computationally at selected points within and near an ice sphere is used to show that the actual physical processes in diffraction of plane waves are consistent with high frequency analogs proposed previously. Failure of the low frequency pulse components to satisfy Snell's law of refraction leads to differences in a detailed description of scattering by an ice sphere.
