传导系统中TE/TM偏振模态的辨析

Discrimination of TE/TM polarization mode in transmission systems

电磁波/光传输特性研究中常用TE/TM偏振描述波的传播模式.不同系统中对TE/TM偏振的定义却存在差别,有时还与s/p态混合使用,使研究者在理论和实验研究中产生概念混淆和结果矛盾的问题.本文从电磁理论出发,对传导系统中可能存在的偏振模式进行深入的推导和分析,解释TE/TM偏振态存在原因和可能状态,对其与s/p态的区别进行比较说明.针对空间偏振态的易混淆问题进行逐一解答.

In the studies of optical transmission characteristics of electromagnetic wave, TE/TM modes are often used to describe the polarization mode of electromagnetic wave. However, the definitions of TE/TM polarization are different in different transmission systems and are often mixed with s/p states, inducing some confusing concepts and contradictory results. Based on electromagnetic theory, we deeply derive and analyze the possible polarization modes in different transmission systems, explain the existent reasons and possible states of TE/TM polarization modes, compare the possible states with s/p states to illustrate the differences, and resolve the confusing polarization problems one by one. This work will sweep away the obstacles for future researches of electromagnetic fields.
