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

摘要

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