摘　　要：矩形波导是工程上最常用的导波结构,也是“电磁场与微波”教学中最重要的内容之一。讨论矩形波导中的模式分类,使用纵向分量法求解电磁场的各分量,利用边界条件确定未知参数,根据本征函数正交性证明矩形波导中不存在纵向电场、纵向磁场同时存在的混合模式。讨论的模式分类内容可以作为电磁场以及微波等相关课程教学中的有益参考。Rectangular waveguide is the most commonly used waveguide structure in engineering,and is one of the most important contents in Electromagnetic Field and Microwave teaching.In this paper the mode classification in rectangular waveguides is discussed.The longitudinal component method is used to solve components of the electromagnetic field,and the unknown parameters are determined by boundary conditions.According to the orthogonality,it is proved that mixed modes in which transverse electric field and transverse magnetic field stayed together do not exist.The derivation of mode classification in this paper can be used by teachers and learners as references when performing relating courses.
