Features of Light Transmission through Monolayer of Structurally Identical Anisotropic Domains with Random Azimuthal Orientation

摘要

Multidomain layers consisting of identical or nearly identical optically anisotropic domains with random in-plane orientation, manifest mixed, partly regular and partly diffuse transmission. In this paper, a simple theoretical model allowing the estimation of the ratio of the scattered and nonscattered components of the transmitted light as well as the polarization state of nonscattered component from optical parameters of a single domain is proposed. In particular, this model describes well the phenomenon of spectral selectivity observed on domain structures consisting of homogeneous birefringent domains. The results of experimental investigations of optical properties of multidomain LC layers, supporting the validity of the proposed model, are presented.
