摘要
"电磁场与电磁波"课程公式繁多,概念抽象,学习难度较大.在无线电测向运动中使用发射电台、接收机设备,需要应用电磁波传播、矢量叠加等相关知识.以该运动为载体,开发无线电测向接收机天线方向图绘制课外实验,将抽象的电磁波理论变得直观.让学生在实践中理解电磁场传播、天线方向图、测试转台、无线方法等相关理论,能够极大调动学生学习兴趣,提升"电磁场与电磁波"课程教学质量.
Abstract
In the course of Electromagnetic Field and Electromagnetic Wave,there are many formulas and abstract concepts,which make it difficult to learn.Meanwhile,the amateur radio direction finding(ARDF)requires the use of transmitters,receivers,and requires the application of electromagnetic wave propagation,vector superposition and other related knowledge.Using ARDF as a carrier,an extracurricular experiment is developed to draw the antenna pattern of radio direction-finding receiver,and the abstract electromagnetic wave theory becomes intuitive.Students can understand the antenna pattern,antenna turntable,test method and other related theories in practice,which can greatly enhance students'interest in learning and improve the teaching quality of Electromagnetic Field and Electromagnetic Wave course.
