电磁波极化教学实验设计与实践

Polarization of Electromagnetic Wave Teaching and Practice of Experimental Design

文章设计了一项电磁场与波课程的新实验,介绍了如何研制开发极化旋转支架、多极化发射天线等实验装置,用线极化天线对多种极化形式的电磁波进行接收测量,组合成一个完整的电磁波极化实验系统。该项新实验解决了电磁波极化实验难以开展的问题,对学生充分理解电磁波极化这一教学难点,起到了极大的作用。

A new experiment is designed for the course electromagnetic fields and waves.This paper presents how to develope experimental equipments such as a polarization of rotation bracket,multi-polarization of the transmitting antenna,etc.Receiving and measuring a variety of forms of electromagnetic wave polarization were conducted by using line polarization antenna,to combine into a complete system of electromagnetic wave polarization experiments.The new experiment to solve the problem that polarization experiments of electromagnetic waves is difficult to carry out.It is useful for students to fully understand the difficulty of teaching that polarization of electromagnetic waves.
