ABSTRACT: We present results of light scattering properties for ensembles of randomly oriented, coated spheroidal particles with an equivalent-volume size parameter kr(eq)=8 and axial ratios e=0.6, 1 and 1/0.6. Müller matrix elements Fij(theta) have been calculated using Waterman´s T-matrix approach, as modified by Peterson and Ström for inhomogeneous particles, together with Mishchenko´s orientation averaging procedure. Differences between oblate and prolate particles with the same short-to-long axis ratio, as well as between spherical and nonspherical scatterers, are outlined. Additional calculations for size parameters 1, 5 and 10 (not shown) have also been carried out for checking purposes.
