Finite-difference time-domain method calculation of light propagation through H-PDLC

Abstract

Presented is the study of the diffraction properties of transmission holographic polymer dispersed liquid crystal (H-PDLC) grating. We constructed a two-dimensional model of H-PDLC film with cylindrical LC droplets. Director distribution inside LC droplets was calculated using the Monte-Carlo method. To calculate light propagation through the film we have solved numerically the Maxwell equations using the finitedifference time-domain method (FDTD). The FDTD analysis of diffraction was performed for s- and p-polarized incident light. Externally applied electric field influence on the diffraction efficiency was studied.
