Light scattering from a sphere with an irregular inclusion

The exact solution for the scattering from a sphere with a nonconcentric inclusion of arbitrary shape and optical constants is derived in terms of a vector harmonic expansion. The only information required of the inclusion is its freestanding scattering coefficients, so the inclusion can be composed of multiple refractive indices or be a set of separate inclusions. We then compare the absorption of glycerin host spheres containing small oblate and prolate carbon spheroids in different orientations.
