Abstract

We have measured both change in phase differences (delta) between ordinary and extraordinary rays passing through liquid crystal cell and dielectric constants (epsilon) of 4- trans-n-hexyl-cyclohekxyl-isothiocyanatobenzene (6CHBT). The results of the studies for different alignment and thicknesses under various electric measuring and magnetic fields are presented. The obtained experimental results and the discussion on the base of the Oseen and Frank elastic continuum theory of a nematic in the presence of electric and magnetic fields make it possible to calculate the vector field of directors in the LC medium.
