Abstract
A numerical method is described which is able to calculate the scattering of polarized light by a large assembly of identical spherical particles, of complex refractive index, such as a colloid or aerosol aggregate. The method takes care of multiple scattering inside the aggregate, except that the criterium for the Rayleigh approximation must be satisfied for the individual particles. It is applied to computer-generated aggregates containing up to 512 particles with various fractal dimensions. The scattered intensities for various polarization directions are studied as a function of the scattering angle and size of the aggregateKeywords
