类比法在“电磁波与天线”课程教学中的应用

Application of Analogy Method in the Course of Electromagnetic Wave and Antenna

相比于其他理工课程,“电磁波与天线”课程的内容多、学时有限,亟须提升课堂的教学效率。类比法是一种利用不同对象具有相同或相似属性进行推理的方法,在电磁学基础课程中已经得到了广泛应用,也为“电磁波与天线”课程教学提供了借鉴。通过列举天线基本辐射元、典型喇叭天线、波导、镜像法,以及电磁波传播、传输和辐射等实例,从教学过程类比、教学内容类比和教学思路类比三个方面进行探讨,帮助学生深入理解和掌握“电磁波与天线”课程内容,提高课堂教学效率和教学质量。

Compared with other science and technology courses,Electromagnetic Wave and Antenna course has many contents and limited class hours,so it is urgent to improve the efficiency of classroom teaching.Analogy is a method of reasoning by using different objects with the same or similar attributes.It has been widely used in the basic course of electromagnetism,which provides a reference for the teaching of Electromagnetic Wave and Antenna.By giving examples of the antenna basic radiation element,the typical horn antenna,the wave-guide,the mirror method,as well as the electromagnetic wave propagation,transmission and radiation,this paper discusses the analogy method in three aspects:the teaching process analogy,the teaching content analogy and the teaching idea analogy,so as to help students deeply understand and master the course content of Electromagnetic Wave and Antenna,and improve the efficiency and quality of classroom teaching.
