Cu was implanted into the pores of alumina film by means of electroplating . with such metal array , the alumina film was expected to work as a wire grid polarizer 将金属cu用电镀方法镀入多孔铝孔中,形成纳米金属列阵,期望象线栅偏振器一样表现出偏振性质。
Among those different methods , the metal - clad planar crystal waveguide polarizer is the most interesting . as a result , it results in the requirement for studying the propagation properties of the electromagnetic field in the metal - clad planar anisotropic media waveguide 其中利用包层金属获得偏振器,越来越受到重视,从而产生了对光在平面各向异性介质金属波导中传输特性研究的需求。

When light travels through this system perpendicularly , the light after the first polarizer will divide into orthogonally polarized ordinary and extraordinary impulses . because of the difference between the extraordinary and ordinary indices of refraction of the crystal , after passing the crystal , the two orthogonally polarized impulses will be different in phase 光线正入射到这一系统,通过起偏振器后的偏振光投射到晶体上时分解为互相正交的寻常光和非常光,两束光由于折射率的不同经过晶体时会有一定的位相差。
