We acquire the distribution of irradiance and phase on the receiver aperture through choosing accurate simulation parameters. At last  the accuracy of simulation is verified through comparing the coherence factor of simulated beam field with that of theoretical field. 2011 IEEE.   V-shaped electro-optic characteristics in FLC gels (EI CONFERENCE) 会议论文 Li J.; Zhu X.; Xuan L.; Huang X. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 The effects of polymer network formed under UV irradiation with electric field application ( 50V  5Hz) to ferroelectric liquid crystal (FLC) molecules orientation and electrooptic characteristics have been studied. The polymer network formed in SmC*phase is anisotropic and fibrils-like  and a typical striped texture was observed in the cell. The FLC gels exhibit a symmetric V-shaped electrooptic characteristics with thresholdless voltage and high contrast ratio (40:1). A theory explanation of the unique properties is given by establishing a molecular orientation model and conducting a computer simulation. A good fitting of the electrooptic dynamic response of FLC gels has been obtained by introducing a potential (bulk anchoring energy) originated from the photo-cured polymer network. 2002 Taylor Francis.
