Numerical T-matrix solution for polarized scattering from clusters of non-spherical scatterers

As the scatterer size is comparable with the wavelength, a rigorous solution of T-matrix is used to calculate the scattering. When scatterers are non-uniformly clustered, the coherency of collective scattering from the scatterers must be taken into account. We employ a multiple scattering formulation of the T-matrix method to develop numerical simulations of polarized scattering from random clusters of spatially-oriented, non-spherical particles. Numerical results present polarized bistatic scattering, backscattering, and the functional dependence on clustering and other physical parameters.
