Abstract

The practical applications of the composite method of determination of nematic liquid crystal material parameters (namely the splay and bend elastic constants, the anisotropy of diamagnetic susceptibility and the boundary tilt angle) is presented in the article. The director field value at the nematics cell boundaries is described as a function of the torque transmitted from the deformed bulk, modeling the coupling between the nematics and the substrate. The method is based on approximate solving the coefficient inverse problem. The applied procedure of determination of material parameters may be divided into three stages.
