Abstract

We consider theoretically light propagation at oblique incidence in absorbing cholesteric liquid crystals in the Bragg mode. Using 2 × 2 matrix procedure, we analyze the eigenmodes in terms of the forward- and backward-propagating eigenwaves inside the isotropic medium bounding the cholesteric liquid crystal. The nature of the eigenmodes in the medium changes continuously from the circular to the linear state with increase in the angle of incidence. Using the appropriate eigenmodes, we studied anomalous transmission in first and second Bragg orders in these systems and its relevance to the reported experimental results. We find some interesting polarization features that arise as a result of the absorption in the cholesteric medium.
