摘　　要：极化是电磁波的重要特性之一,对于正确应用电磁波有着重要的作用。本文以平面电磁波为例,对极化问题作了分析,总结了不同极化方式之间的理论统一性,给出了判断平面电磁波极化方式的一般流程。文中还介绍了判断圆极化和椭圆极化旋向的图形方法以及简便计算方法,既有利于对极化概念的理解,也使极化分析与判断变得更加容易。Polarization is one of important characteristics of electromagnetic waves.It plays critical roles in different applications of electromagnetic waves.In this paper,we analyze and discuss polarization theory of plane wave comprehensively.The unity of different polarization theories is summarized systematically,and a general polarization identification procedure is provided.The proposed simple graphical methods and calculating approaches are not only conducive to the understanding of the polarization concept,but also to make the polarization analysis and identification easier.
