Analytical and numerical algorithm for calculating the radiation intensity in a two-dimensional inhomogeneous medium

The authors consider the boundary-value problem of radiation transfer in a two-dimensional inhomogeneous medium with a given optical thickness and a spherical characteristic scattering curve. The simplicity of the computer realization of the algorithm presented, its theoretical validity, and comparison between this one and other algorithms suggest that this algorithm effectively supplements the existing algorithms for solving the equation of transfer in a two-dimensional inhomogeneous medium.
