本文就是在此背景下，利用金属波导和单轴晶体的一些特性，结合麦克斯韦方程组和波导的边界条件，从三种不同的情况研究了光在对称平面单轴晶体金属波导(波导层是单轴晶体，两个波导界面均为金属)内的传输特性，其主要贡献为，首次解析地得到了这种波导结构下模式场的精确解，并发现了一些有用的特性： ( 1 )模式场的性质因单轴晶体的性质不同而异； ( 2 )当单轴晶体光轴位于波导界面法方向与传输方向构成的平面内时，波导中传输te波和tm波，只不过其主模因单轴晶体的性质不同而异，当波导层介质为负单轴晶体时，波导主模是te波主模，而波导层介质为正单轴晶体时波导主模是tm波主模。 ( 3 )当单轴晶体光轴位于波导面内时，对于正单轴晶体，波导的主模是横电波te _ 0模，任何频率的光波均可激励该模式；当光波波长满足一定条件时，波导内传输单模，否则，将激励起高阶模式，高阶模即匪te波，也匪tm波，而是两者耦合而成的混合模。 |
