电磁波极化和天线极化的教学研究

摘要

The polarization of electromagnetic wave is an important concept in courses of Electromagnetic Field ＆ Wave and Antennas ＆ Radio Propagation. This paper analysis some problems in the process of teaching such as polarization mismatching, circular polarization used to eliminate ghosting, the propagation of circularly polarized wave, the reception of linear polarization wave, the polarization form of current element and so on. These analyses can contribute to understand and grasp the concept of electromagnetic polarization. The author hopes that it can improve the teaching quality of the polarization of electromagnetic wave for studends.%电磁波极化是“电磁场与电磁波”和“天线与电波传播”课程的教学重点。本文详细分析了在电磁波极化教学中易引起误解的几个常见问题，如极化匹配、圆极化波消除重影、圆极化波的传播、线极化波的接收和电流元的极化形式等，澄清了相关的概念。这些分析有助于加深学生对电磁波极化概念的理解和掌握，最终有效提高课程的教学质量。
