摘　　要：根据二维光子晶体的周期性结构对于移动通信中的天线信号进行补偿,对电磁波而言,在介电质中传播,所遇介电常数反差如同电子在晶体中的周期性位势.基于电子束微影法通过光阻进行基板刻蚀技术经曝光显影后所制成的金属氧化物补偿材料压制成薄膜结构,利用二维光子晶体所形成的周期性排列结构,制作薄膜材料,对射频电波进行滤波.在介质层表面的电场分布可以通过边界条件求得,对材料表面的TE波及TM波分别进行分析.通过常用材料及成熟的制造技术实现传统的光学晶体补偿结构,减少天线在不同方向上所形成的偏差,并增强相应的极化透射强度.In this paper, we design a Signals from antenna transmitter can be compensated with the two -dimensional photonic crystal based periodical structure. As for the electro magnetic wave, the difference of permittivity or permeability between materials is the same as electron transmission during periodical potential. The e- beam approach can etch the substrate with metal oxide compensation thin films. Utilizing the periodical structure of two - dimensional photonic crystal, we filter the miscellaneous polarization of the incident wave. The electric field can be calculated with boundary conditions, and the energy distribution between TE and TM mode are analyzed. The compensation structure can be produced with sophistic fabrication technology to achieve a higher efficiency of the polarization filter.
