Bragg-Berry cholesteric deflectors are one of the micro- or nano-patterned liquid crystals. The Bragg-Berry cholesteric deflectors exhibit unique selective reflections, unlike conventional cholesteric liquid crystals. In this study, we calculated the angular dependence, bandwidth, and polarization of selective reflection from the Bragg-Berry cholesteric deflectors by the finite difference time domain (FDTD) method.
