摘要
作为《电磁场与电磁波》教学难点之一,分层媒质中的平面波这一内容较为抽象。本文就这一内容进行了详细分析,导出了一种基于二端口网络级联的方法,并给出了具体应用实例。该方法具有物理概念明晰、易于仿真模拟等优点,有利于该内容的形象化教学和学生对行波、驻波等概念的直观理解。
As one of the difficult teaching points in electromagnetic fields and waves, the content about plane wave in multilayered media is too abstract for study. In this paper, the theory about plane wave in multilayered media is analyzed in detail, and a method based on equivalent cascaded two-port networks is proposed with specific applications. Compared with the traditional method, the proposed method is more convenient for numerical simulation and has more clear physical meaning, which is helpful for the visualized teaching of this content and will help the students to comprehend relative conceptions such as travelling wave, standing wave and so on.
