A new Monte Carlo algorithm for estimating the angular distribution of scattered polarized radiation based on orthogonal expansion

摘要

Monte Carlo algorithms for studying the angular dependence of the intensity of radiation transmitted through a layer of a substance on the basis of expanding the density of the corresponding angular distribution of quanta in polynomials orthonormalized with Lambert weight are developed; optimization is implemented according to the criterion of computational complexity. The algorithm makes it possible to fairly accurately estimate even a small influence of polarization and the deviation of the angular distribution under examination from the Lambert distribution.
