Orientational effect of a surface light wave on liquid crystals
Zel'dovich B. Ya., Tabiryan N. V.
It is predicted that the nonpropagating light wave appearing with total internal reflection and localized near the interface has a strong effect on a nematic or cholesteric liquid crystal mesophase. The change in the Grandjean structure of the cholesteric liquid crystal is manifested as a change in pitch. On the other hand, the planar structure of the nematic liquid crystal becomes a chiral structure under the action of the wave.
