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 finite- difference 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.

Keywords: polymer dispersed liquid crystal, Monte-Carlo simulation, electric switch, finite-difference time-domain method.
