Nematic deformation for nonuniform axially-symmetric electric field. Theory and calculation

The paper presents the results of theoretical and calculation investigations of homeotropic liquid crystal microlens. In usual continuum theory the equation of orientation equilibrium of molecules is considered. In our paper we obtained such an equation to two-constant approximation with electrical field influence at axial symmetry. This equation was calculated and the optical properties of LC-microlens was investigated numerically. The phase profile retardation is the main property of microlens and was compared with the experimental data. Numerical agreement with experimental data was obtained
