“电磁场理论”课程教学中两个实例的应用

Two Examples Applied to Teaching of Electromagnetic Field Theory

“电磁场理论”课程是信息工程专业和电气工程及自动化专业的一门重要的专业基础课,该课程是有名的难学课程,学生在学习的过程中畏难情绪大,没有积极性。为激发学生学习“电磁场理论”课程的兴趣,提高教学效果,在授课过程中增加电磁场的应用实例是有效的手段。本文给出了教学过程中引用的两个实例:用介质中电磁波传播理论,分析了矿井煤岩介质中电磁波的传播特性,给出了有用的结论,使学生看到了电磁场理论的应用前景,提高了学习的兴趣,收到了很好的效果。

Electromagnetic field theory is an important course to information specialty, electric engineering and automatization specialty. It is an well-known difficult course. The students feel difficulty and have no interest in studying this course. Therefor we apply examples to arouse students' interest for teaching this course. It is proved to be a good method. Two examples are introduced in this paper. They are about characters of electromagnetic wave propogation in coal rock medium. Students can see foreground of electromagnetic field theory from these examples, so they are interest in study.
