用于平面电磁波极化旋向判断的追赶法

The Chasing Method Used in the Judgement of Polarization Spin Direction of Plane Electromagnetic Wave

传统判定电磁波极化的方法比较复杂且容易出错。本文提出一种利用电场矢量在两个垂直方向的投影分量的相位差异进行判断的方法,即追赶法。该方法不需要坐标轮换即可直接判断出沿任意方向传播的平面波的极化旋向,使用范围广并且容易掌握。

The traditional polarization judgement method of electromagnetic（ EM） wave polarization is complex and easy to make mistakes. A method used in the judgement of polarization spin direction of EM wave is proposed based on the phase difference of two orthogonal electric vector weights,that is chasing method. This method can be used to directly judge the polarization spin direction of EM wave that propagating along arbitrariness directions without coordinate alternation. It can be used in a wide range and easily to be mastered,so the efficiency of teaching and studying is improved.
