Light scattering by large-scale director inhomogeneities in filled liquid crystals

Light scattering by large-scale director inhomogeneities in filled liquid crystals
This paper presents the results of a theoretical study of light scattering cross-sections in liquid crystals containing small spherical particles, using the anomalous-diffraction approach. We consider the cases of separate particles and particle network in nematics. Particularly it is shown that for a dipole director configuration around the particle the light scattering is about two orders of value stronger than for a Saturn ring one; for a particle network the nature of the network domain orientational distribution influences the intensity of light scattering, but has little effect on its angular dependence.

Abstract

This paper presents the results of a theoretical study of light scattering cross-sections in liquid crystals containing small spherical particles, using the anomalous-diffraction approach. We consider the cases of separate particles and particle network in nematics. Particularly it is shown that for a dipole director configuration around the particle the light scattering is about two orders of value stronger than for a Saturn ring one; for a particle network the nature of the network domain orientational distribution influences the intensity of light scattering, but has little effect on its angular dependence.
