Analytical calculation of the radiance distribution inside and outside a layered sphere or cylinder generated by a point source

Abstract

We consider an anisotropically scattering layered cylinder or sphere illuminated by a point source. The scattered field generated by these bodies is calculated in terms of the appropriate mode decomposition of the radiance. This leads to mode-expansions for the radiance which are very similar to the mode expansions derived for the diffraction- scattering problems of classical mathematical physics.
