摘　　要：针对"电磁场与电磁波"课程理论性强、概念抽象的特点,对该课程的实践环节进行了研究,设计了验证型和综合型等实验.其核心实验设计思想是用微功率白炽灯和高频检波电流表作为微波频段电磁波接收指示器,替代传统中价格昂贵的微波接收设备,并通过生动形象的实践环节的具体实施,达到了实验辅助与深化课堂教学的效果,激发了学生对理论知识的学习兴趣.For the features of profound theories and abstract concepts of the course of electromagnetic field and wave, the practice of the course is studied. Micropower incandescent lamp and high frequency detection ammeters are used as microwave frequency electromagnetic receiving indicators to replace the traditional microwave receiving equipments, which are expensive. The teaching with experiment auxiliary is realized, which deepens the classroom teaching and stimulates the interest of the students in the theoretical knowledge learning.
