摘　　要：根据电磁兼容相关课程特点,针对电磁兼容教学过程中缺乏能够完整且具象演示电磁耦合路径实验教学系统问题,从电磁兼容基本理论出发,参考微带线的耦合和辐射理论,设计并制作了一套电磁耦合路径可视化实验教学系统,实现了场-场、场-路、路-场、路-路等电磁耦合路径的可视化。该实验教学系统结构简单,不需要外部干扰源,能够利用简单的实验仪器一次性实现四种耦合路径的可视化展示,展示的耦合效应明显、直观,有助于加深学生对电磁兼容“三要素”中耦合通道这一要素的理解,并为后续相关课程教学奠定基础。Based on the characteristics of electromagnetic compatibility related courses,aiming at the problem of lacking a complete and concrete experimental teaching system that can demonstrate the electromagnetic coupling paths in the course of electromagnetic compatibility teaching,Starting from the basic theory of electromagnetic compatibility and referring to the coupling and radiation theories of microstrip lines,a visual experimental teaching system of electromagnetic coupling paths is designed and made,achieving the visualization of field-field,field-circuit,circuit-field and circuit-circuit electromagnetic coupling paths.The experimental teaching system has a simple structure and does not require external interference sources.It can use simple experimental instruments to realize the visual display of four coupling paths at one time,and the coupling effects are obvious and intuitive.The experimental teaching system is helpful to deepen students’understanding of the coupling channels in the“three elements”of electromagnetic compatibility,and lays a foundation for the subsequent teaching of related courses.
