Part of the book series: Lecture Notes in Nanoscale Science and Technology ((LNNST,volume 18))

Abstract

Extinction and polarization state of light transmitted through a polymer-dispersed liquid-crystal (PDLC) film with nanosized, spherical, nonabsorbing nematic droplets is investigated theoretically. Scattering properties of a single droplet are described by the Rayleigh–Gans approximation. Propagation of coherent light field is described in the frame of the Foldy–Twersky theory. The concept of multilevel order parameters is used. Equations for extinction coefficients, phase shift, and polarization of transmitted light for layers with random and oriented droplets are written and discussed. Conditions for circular and linear polarization of light are determined and investigated. Polarization-independent focusing of light by films made of PDLC is considered. The results are in good coincidence with the known experimental data.
