摘　　要：在介绍矩形波导模式谱图一般表达式的基础上,分析了多模传输波导的等效网络,提出了检测微波激励和传输系统中多模传输的分式线性变换检测法。文章给出了检测的具体实例和试验数据,实验结果与理论分析相吻合,表明在一定条件下,标准三公分波导工作频率高达16GHz仍是单模传输。On the basis of the general expression of rectangle waveguide mode-spectrogram, the equivalent network is analyzed in the paper, and the linear fraction transformation method for detecting the multi-mode transmission in rectangle waveguide is introduced. Examples and experimental data are also given. The experimental results are in good agreement with the theoretic results. The results indicate that the operating frequency of the standard 3cm waveguide is able to reach 16GHz with the dominant mode transmission in specific conditions.
