Director distribution of nematic liquid crystals in a cylindrical cavity under electric field perpendicular to the cylindrical axis
摘要
Abstract
The curved liquid-crystal system has different characteristics from the planar liquid-crystal system.In this paper,the director of nematic liquid crystal in a cylindrical cavity is studied by applying a uniform electric field perpendicular to the axis of the cylinder under the strong axial anchoring boundary condition.Based on the elastic continuum theory of liquid crystal,the equilibrium equations and boundary conditions of the system are given.The analytical solution of the threshold electric field for the deformation of the director is obtained.It is found that different elastic constants will lead to the asymmetry of the change of the director on the cross section of the cylindrical cavity.It provides a more accurate theoretical analysis for the experimental research of photonic crystal fibers.关键词
