Electrically controlled light refraction in a nematic liquid crystal (LC) with homeoplanar orientation possessing different thicknesses has been investigated at angles of light incidence on the layers exceeding the angle of total internal reflection

The refraction of light, i.e., the turn of an extraordinary ray in the liquid crystal layer similar to total internal reflection at an interface between two media, has been studied in a cell with the homeoplanar orientation of the director. The rise,

The electric field-induced reorientation of a nematic liquid crystal in cells with a planar helicoidal or a homeoplanar structure of a director field is studied theoretically and experimentally. The dependences of the capacitances of these systems on

The pretilt angle of the director at the liquid crystal–glass interface is determined with the polarimetric and crystal rotation methods. The polarimetric method has been modified with the aim of increasing the measurement accuracy. The results obt

We investigate the propagation of the extraordinary ray in a cell with a chiral liquid crystal at oblique incidence. For a 180° twist cell, we study the dependence of the minimum incidence angle at which the light does not yet pass through the cell

The influence of an electric field on the trajectory of an extraordinary light ray in a layer of a chiral liquid crystal (LC) with a 180° turn of the director is studied. In the absence of the electric field and at a large angle of incidence the ray

The effect of an alternating electric field on the trajectory of an extraordinary light wave in a layer of a chiral liquid crystal with a 180° turn of the director is studied. In this structure, in the absence of the field and at a large angle of in

A polarimetric method is proposed to determine the tilt angle of the local optical axis of a liquid crystal at layer boundaries. The method is based on the measurement of the azimuthal polarization angles of light waves passed through a liquid-crysta
