| 传输线的等效集总电路模型有助于理解和掌握传输线的基本概念,并可用于电特性的仿真分析。本文分别探讨了在教学过程中需拓展的两个重要知识点。其一,在高频工作情况下,需要对含有频变分布参数的传输线进行准确建模,获取相应的等效集总电路模型；其二,在分析多导体构成的耦合传输线时,等效集总电路模型同样值得探究。 |
| 英文摘要: |
| The equivalent lumped-element circuit model is helpful for understanding and mastering the basic concepts of transmission lines, and it can also be used for the analysis of electrical characteristics. This paper discusses two important points that need to be expanded in the teaching process. Firstly, in the case of high-frequency operation, it is necessary to accurately model the transmission line with frequency-dependent parameters to obtain the corresponding lumped-element circuit model. Secondly, when analyzing the coupled transmission lines composed of multiple conductors, the lumped-element circuit model is also worth exploring. |
