Paper Abstract

A new field-off technique for measuring polar anchoring energy of a nematic liquid crystal on a solid surface is offered. The technique is based on estimating anchoring strength from the experimental conditions under which symmetrical configuration of nematic director field occurs in wedge cells with the boundary conditions asymmetrical in the anchoring strength and easy axis orientation. The presence of symmetry elements is determined from the relation between the LC cell transmittances for various polarized components of incident light. The feasibility of the technique is proved by numerical simulation.
