Electromagnetic scattering by magnetic spheres
Abstract
A number of unusual electromagnetic scattering effects for magnetic spheres are described. When epsilon = mu, the backscatter gain is zero; the scattered radiation is polarized in the same sense as the incident radiation. In the small-particle limit, conditions are described for zero forward scatter, for complete polarization of scattered radiation in other directions, and for asymmetry of forward scatter to backscatter. The special case in the small-particle limit of m = 1, i.e., mu = 1/epsilon, provides interesting special instances of complete polarization and forward-scatter-to-backscatter asymmetry.
