在模式耦合理论的基础上，对过模圆波导模式耦合进行了系统研究，得到了最优几何参量。采用不同的相位重匹配方法和选择相应的几何结构，对TM01TE11、TE01TM11、TE0nTE01、TE01TE11模式变换器进行了优化分析，以此结果可设计出相应的紧凑、高效、宽带毫米波过模波导模式转换器。

[Abstract]
Based on the mode coupling theory, the design of the geometric configuration for an TM01TE11,TE01TM11,TE0nTE01 and TE01TE11 overmoded circular waveguide mode converter with different phase rematch and structure is given to obtain more acceptable geometry parameters. The regulation of the radius of the circular waveguides, the curvature and frequency of bent circular waveguides, and the bandwidth also are obtained. With the results, a compact, efficient and wideband circular waveguide mode converter can be designed.
