Mishchenko, M.I., J.M. Dlugach, and D.W. Mackowski, 2016: Electromagnetic scattering by fully ordered and quasi-random rigid particulate samples. J. Opt. Soc. Amer. A, 33, no. 11, 2144-2149, doi:10.1364/JOSAA.33.002144.

In this paper we have analyzed circumstances under which a rigid particulate sample can behave optically as a true discrete random medium consisting of particles randomly moving relative to each other during measurement. To this end, we applied the numerically exact superposition T-matrix method to model far-field scattering characteristics of fully ordered and quasi-randomly arranged rigid multiparticle groups in fixed and random orientations. We have shown that, in and of itself, averaging optical observables over movements of a rigid sample as a whole is insufficient unless it is combined with a quasi-random arrangement of the constituent particles in the sample. Otherwise, certain scattering effects typical of discrete random media (including some manifestations of coherent backscattering) may not be accurately replicated.
