| Abstract: | The change in the orientation of the director of a nematic liquid crystal in a light wave field under a uniform illumination is analyzed. A system of equations for the distribution of the director angle of inclination is derived for the case of normal incidence. This system accounts for the finite energy of interaction between the nematic and substrate. The dependence of the director distribution profile on the incident light intensity and cohesion energy is studied at fields considerably above the threshold. |
