One dimensional stationary states with constant electrical induction in ferroelectric liquid crystals

Abstract In a ferroelectric liquid crystal, it is the electrical induction, D, and not the electric field, E, which is independent of the space coordinate in a one dimensional analysis. This causes, at small applied voltages, stationary states which have a homogeneous orientation and are field free over most of the liquid crystal. At higher voltages homogeneous field states with zero, one or two surface layers may exist.
