ABSTRACT: The Extended Boundary Condition Method (EBCM), or T-matrix method, has been applied to the determination of scattering cross sections of coated spheroidal particles in random orientation. We report the effects of varying size and core/shell ratio for a number of axial ratios. Some considerations are made on the different scattering properties of equal-volume prolate and oblate spheroids, as well as on the effect of nonsphericity on thin-shell coated systems. We discuss some convergence strategies for coated-particle EBCM calculations.
