Abstract

Optical anisotropy na = neno of nematic liquid crystals (NLC) is usually large enough, so the wave with an eigen polarization follows adiabatically the local orientation of the optical axis, i.e., of the director n(R): ed(R) = n(R) − k(kn)k2, e0(R) − [kee], where k is the wave vector. The present report deals with the phase which a- or e-waves acquire passing through the NLC cell with inhomogeneous orientation of director inside it.
