Reorientation of director of nematic liquid crystals, doped with azodyes, under light and low-frequency fields

An interaction of the director of NLCs, doped with mono- and diazodyes and showing the sign-inversion nonlinearity, with the simultaneously applied light and low-frequency electric fields has been studied using the technique of the aberrational self-action. Mathematical simulation of this interaction was performed. A fair fit to the experimental data was obtained.
