A method describing light propagation in a plane-parallel light-scattering layer with large concentration of homogeneous particles is developed. It is based on the radiative transfer equation and the doubling method. The interference approximation is

We retrieve the radius R, real n and imaginary k parts of the refractive index of homogeneous spherical particles using angular distribution of the light-scattering intensity. To solve the inverse light-scattering problem we use a high-order neural-n

A model to describe light transfer in polymer dispersed liquid crystal (PDLC) films has been developed. It takes into account the anisotropy of the nematic liquid crystal droplets, their polydispersity, multiple scattering, and Fresnel reflection at

We present the results of numerical modeling of the angular distribution of radiation at the boundaries of and inside the layer with oriented spheroidal particles for the case of oblique incidence of a parallel beam of radiation upon the layer. The o

We consider a method for solving the radiative transfer equation (RTE) based on the representation of the azimuth-averaged phase function as a combination of a smooth phase function and the Dirac delta function. Unlike the traditional transport appro

The results of numerical modeling of diffuse reflection and transmission by layers of oriented spheroidal particles (whose rotation axes are normal to the layer surface) with oblique incidence of a a parallel beam of radiation on the layer are presen
