摘　　要：散射参量处理微波网络中入射波和反射波之间的关系,是描述微波网络特征的重要参数之一。针对教学中在给出散射参量定义后,对其所蕴含的物理概念缺乏从实例应用方面的分析,以一段均匀传输线模型为例,采用未加源和加源的散射参量定义法、奇偶模法和级联网络法分别推导其散射参量,并验证了其结果的一致性。Scattering parameters relate the voltage waves incident on the ports to those reflected from the ports,which are one of the important parameters used to describe the characteristics of microwave networks.In view of the lack of practical analysis of the physical concepts implied in the definition of scattering parameters in teaching,taking a uniform transmission line model as an example,four methods are used to derive its scattering parameters,including the scattering parameter definition method without and with sources,the odd-even method,and the cascade network method,respectively.The consistency of the results is validated.
