Simulation of multiple scattering in the systems with complicated phase function

Abstract

a b s t r a c tWe consider simulation of multiple scattering of waves in isotropic and anisotropic media. The focus is on the construction of the phase function interpolation for the single scattering. The procedure is based on the construction of the adaptive partitioning of the angular variables that determine the phase function. The developed interpolation method allows us rather quickly to perform calculations for systems with very complicated phase function. Application of the proposed method is illustrated by calculating the multiple scattering of light in a nematic liquid crystal (NLC) which presents the uniaxial anisotropic system. For this system the grid corresponding to the adaptive partitioning is constructed and the transition to the diffusion regime for the photon distribution is presented.

Analytical method to study multiple scattering characteristics in participating media

“…In addition, light scattering can be considered as redirection of electromagnetic waves colliding with obstacles or inhomogeneous media. It is essential in crystals, the atmosphere, and biological tissue [1]. Cirrus microphysical and scattering properties have large impacts on how cirrus affects radiation [2].…”
