电磁波极化的图形化复数教学研究

Research on Graphic Visualization Complex Teaching of Electromagnetic Wave Polarization

本文利用电磁波的基本特性,将空间任意方向传播的电磁波变换到沿Z轴正方向传播的形式,然后采用矢量空间和复平面重合的形式来描述电场强度矢量合成,从而将电磁波的极化问题转换成正、反转复数的分析,利用图形直观地展现电磁波的极化规律,实践表明,图形化复数教学方法有助于学生理解电磁波的极化,也为"电机学"课程空间磁势分析方法打下基础。

Spatial coordinate transformation is firstly introduced to make the wave propagation align with the direction of Z-axis based on orthogonal property of field and wave vectors in this paper. Then combination of vector and complex space is adopted to describe the electric field waveform as rotating complex vectors in counterparts. Thus graphic visualization is illustrated to analyze the polarization of the electromagnetic wave,which helped students to deeply understand the concept of polarization and solidify foundation for further analyzing spatial magneto-motive force of Electric Machinery.
