Matlab在“电磁场与电磁波”课程可视化教学中的探索——以平面电磁波在介质交界面处的反射与透射分析为例

The Application of Matlab in the Visual Teaching of the Course of “Electromagnetic Field and Electromagnetic Wave”—Taking the Reflection and Transmission Analysis of Plane Electromagnetic Waves at the Interface of the Medium as an Example

电磁场理论有着丰富的科学内涵和应用领域,广泛应用于包括广播、电视、雷达、卫星通信导航定位等,催生了信息时代的到来。电磁场相关知识学习过程中涉及的理论推导多、概念多且抽象。利用Matlab程序对平面电磁波在介质界面的反射与透射进行可视化,有助于学生理解和掌握该物理过程,也为《电磁场与电磁波》课程中其他知识点的教学提供有益借鉴。

Electromagnetic field theory is widely applied in scientific contexts and industrial fields such as radio, television, radar, satellite communications, navigation and positioning, etc., which ushered in the information age. During the learning of electromagnetic fields, there are many abstruse derivations and concepts as obstacles for students. Using the Matlab program to visualize the reflection and transmission of plane electromagnetic waves at the interface of the medium will help to improve students’ understanding and mastery of the physical process, and also provide a useful reference for the teaching of other knowledge points in the Electromagnetic Field and Electromagnetic Waves course.
