Depolarization effects of light reflected by domain-structured cholesteric liquid crystals

摘要

The simulation of light reflected by polymer-dispersed cholesteric liquid crystals is carried out using a model that takes into account the domain structure of the layer. The model is based on the 4x4 matrix calculation method of Berreman. One considers different orientations of the helical axis in multi- and single-domain configurations. The assumption of the distribution of helical axis orientations in the multi-domain model allows the description of optical properties of multi-stable director configurations. Polarization properties of the reflected light are investigated. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 10]
