Abstract
The depth mode of light propagation in a 2D-medium with strong absorption and sharply- anisotropic scattering is studied analytically outside the framework of the small-angle diffusion approximation. We propose and realize a regular procedure for optimum determination of the parameters of a postulated approximate angular spectrum in the depth mode. The dispersion in the depth mode and the depth damping coefficient are found. Our results are in good agreement with the exact solution to the transport equation written in the quasi-diffusion approximation, that has been obtained recently in the particular case of the Henyey-Greenstein phase function.
