摘要
本文就"电磁场理论"课程中电磁波全反射现象的教学进行了深入分析,从电磁波在介质分界面上的反射和折射入手,导出全反射条件,分析全反射时透射波的波场和能流特点,以及给出全反射现象在实际中的应用实例。我们通过这种教学过程使学生深刻掌握了全反射这一重要知识点,在实践中取得了良好的教学效果。
The total reflection of the electromagnetic wave is an important phenomenon. In this paper, the teaching contents and teaching methods about the total reflection are analyzed and discussed in details. We analyze the re- flection and transmission of electromagnetic wave on the interface between two medium, and derive the condition of total reflection and the characteristic of refractive wave , and we also gave some examples of applying total reflec- tion. These series teaching contents let students understand the total reflection very well.
