Estimation of Optical Properties of “Soft” Radially Inhomogeneous Ellipsoidal Particles

Abstract

The Rayleigh–Gans–Debye and anomalous diffraction approximations are used to formulate necessary and sufficient conditions of optical equivalence of randomly oriented, radially inhomogeneous, optically “soft” ellipsoidal particles and polydisperse radially inhomogeneous spherical particles. Consequences of optical equivalence are used as a base for the optical classification of isotropic ensembles of soft ellipsoidal particles. The correctness of the classification is illustrated by calculations using the T-matrix method and Mie theory.
