Paper Abstract

The derivation of the Sh-matrices using the T-matrix method allows the shape-dependent parameters to be separated from size- and refractive-index-dependent parameters. This separation also allows for the surface integrals to be solved and for analytic solutions to the light-scattering from some irregular morphologies to be found. In this manuscript we derive solutions for capsule-shaped and bi-sphere particles. We analyze the two-dimensional patterns resulting from these two different simulants of B. subtilis spores. The large differences between the patterns suggest that simple approximations to complicated particles may not be adequate.
