Abstract
The static deformations of a flat nematic liquid crystal cell (modelled as a planar layer infinitely extended in two directions) may be quite precisely described in the frame of the theory proposed subsequently by F.C. Frank, J.L. Ericksen and--in final form--by F.M. Leslie. The deformations are forced by cell boundaries and by external magnetic and electric fields. The quantitative prediction of phenomena is not possible until the nematics material parameters are known; such as the splay and bend elastic constants, the anisotropy of diamagnetic susceptibility, the electric permittivities and the tilt angle of nematics molecules at the boundaries. A stable method for the determination of them is proposed in the work.
