External Electric Fields Action on Liquid Crystalline Layers, Modifying Their Degree of Order (original) (raw)

Abstract

Two mesogens were considered in this study; a thermotropic one, named N(p’-methoxy-benziliden)-p-n’-butyl aniline and a lyotropic liquid crystal, poly (phenyl-meth-acrylic) ester of cetyloxybenzoic acid in tetra chloromethane. Their birefringence was measured with a Rayleigh interferometer in absence and in presence of an electrostatic field with variable intensity. The results were transformed in continuous functions in order to be used to simulate the transmission factor for Wood multistage filter. The results for simulation of Wood filters based on N-(p’-methoxy-benziliden)-p-n’-butyl aniline are given in this paper.
