Polarizability of a tri-isotropic sphere - art. no. 046609

This report presents the polarizability matrix of a tri-isotropic sphere. A tri-isotropic material exhibits coupling between electric, magnetic, and i n addition, a third kind of material response. Each of these three fields c reates three different kind of polarizations. The paper derives the polariz ability components of such a sphere in vacuum and makes physical interpreta tions of the results for the copolarizabilities and cross polarizabilities.
