T-matrix theory of light scattering by uniformly anisotropic spherical scatterers

We extend the T-matrix approach to light scattering by spherical particles to the simple case in which the scatterers are optically anisotropic. Specifically, we consider the spherical particles that are uniformly anisotropic. We find that the T-matrix theory can be formulated using a modified T-matrix ansatz with suitably defined modes. We derive these modes by relating the wave packet representation and expansions of electromagnetic field over spherical harmonics. We present preliminary results of numerical calculations of the scattering by spherical droplets. We concentrate on cases in which the scattering is due only to the local optical anisotropy within the scatterer.
