Abstract:
We report Monte Carlo simulations based on the Lebwohl-Lasher model for characterizing the molecular director configuration in a nematic liquid crystal cell presenting various anchoring conditions. In order to investigate the behaviour of a liquid crystalline system having two opposite anchoring directions, in our study we simulated an anchoring regime with half homeotropic and half planar boundary conditions, the cell electrodes having parallel striped layers. Simulations were also performed concerning with the light passing through the planar and homeotropic periodical regions of the nematic cell and a mapping of the transmitted intensity was obtained for several ambient temperatures.
