Dielectric polarizability of a sphere with arbitrary anisotropy.
The polarizability of a dielectrically anisotropic sphere is studied. The anisotropy is general, consisting of a symmetric and an antisymmetric part of the permittivity dyadic. The polarizability is also dyadic, with its components depending on the relations of the permittivity components of the material. In certain special cases the components of the polarizability matrix decouple and become functions only of the corresponding permittivity components, but in general all nine polarizabilities depend on all nine permittivities.
