Optical Rotation of a Nonideal Liquid Crystal Superlattice

Abstract
The problem of finding polariton states (necessary for calculating of gyrotropic char-acteristics) in space-dispersive superlattices is not solved yet. At the same time the specified quantities can be approximately evaluated if the widths of layers comprising a multilayer material are much bigger than the characteristic scales of space dispersion. In that case the con-tribution of each layer to gyrotropy can be regarded as independent. Thus the corresponding optical quantities can be expressed through the layers’ gyrotropic characteristics. In the present research this approach is applied to the calculating of the specific rotation angle of plane of polarization of light propagating through a nonideal optically active 1D-superlattice, containing arbitrary number of foreign layers, which varies in composition as well as in lay-ers' width.
