电磁场与微波技术实验教学改革和探索

Teaching Reform and Exploration for Electromagnetic Theory and Microwave Measurement Experiments Course

电磁场与微波技术实验课程在学生学习电磁场与电磁波的基本理论、基本知识、基本技能,培养学生分析问题和解决问题的能力等诸多方面发挥了重要的作用。通过该实验课程的学习,不仅验证了电磁场与微波的抽象理论,而且培养了学生通过检测和测量手段来解决电磁场与微波实际问题的能力。北京邮电大学从实验内容以突出通信特色为出发点,对电磁场理论与微波技术实验的教学进行了深入探索和完善。内容方面完善了电磁波的传播测量、波导传输线测量等传统实验内容,又增加了微波收发系统、低噪声放大器设计等综合性实验内容,改革了天线方向图测量的测量手段,改革后的实验内容更加适应当前社会对相关专业人才需求。实践表明:通过教学实验的深入改革,学生对于知识的掌握和微波设计能力都有了较大提高。

Electromagnetic theory and microwave measurement experiments course has great effects on students＇ studying the basic theories of electromagnetic field and wave,the elementary knowledge and the basic experimental skill,and training students＇ ability to analyze and solve problems. By course study,students not only verify the abstract theories of electromagnetic field and microwave measurement,but also improve the ability to solve practical problems of microwave detection and measurement. Beijing University of Posts and Telecommunications（ BUPT）,starting with experiment content,explores the teaching of electromagnetic theory and microwave technology experiment course in order to highlight the communication characteristics. In the aspect of content,BUPT enriched the traditional experiments,such as measurement of electromagnetic wave transmission and waveguide transmission line measurement,added comprehensive experiments,such as microwave transceiver system measurements,low noise amplifier design,reformed the experimental method of antenna pattern measurement,which met the current demanding for cultivating talents. The practice shows students＇ abilities have been improved greatly in some aspects,such as mastery of knowledge,comprehensive design and microwave circuit application.
