斜激结构手征材料的圆形布喇格现象的电控显示理论。第2部分:任意直流电场
Theory of electrically controlled exhibition of circular Bragg phenomenon by an obliquely excited structurally chiral material. Part 2: arbitrary dc electric field
摘要:
对平面波在电光结构手征材料(SCM)平板上反射和透射边值问题的数值研究表明,SCM的圆布拉格现象的表现不仅可以由直流电场的符号和大小来控制,而且还可以由其相对于SCM螺旋非均匀性轴的方向来控制。从而扩大了圆偏振滤光片电控的可能性。
英文摘要:
Numerical examination of the solution of the boundary--value problem of the reflection and transmission of a plane wave due to a slab of an electro--optic structurally chiral material (SCM) indicates that the exhibition of the circular Bragg phenomenon by the SCM can be controlled not only by the sign and the magnitude of a dc electric field but also by its orientation in relation to axis of helicoidal nonhomogeneity of the SCM. Thereby, the possibility of electrical control of circular--polarization filters has been extended.
