Positive or negative values of the amplitude reflectivity r_ px and r_ py gave rise to the real phase and orientation of the reflected filed relative to the incident one. 振幅反射率rpx和rpy的正负,真实地反映反射光中相应电矢量分量相对于入射光的电矢量的位相变化和方向。
For multi-layer structure with a nematic liquid crystal ( NLC) film, the amplitude reflectivity is ob-tained by Maxwell equations and boundary conditions. 并利用Maxwell方程组和边界条件,求出了含液晶多层膜结构的振幅反射率。
