矩形波导与圆柱波导或圆柱谐振腔间的小孔耦合

本文讨论了三种不同系统的小孔耦合的近似解法:矩形波导与圆柱波导的同轴耦合,矩形波导中的TE₁₀型波与圆柱谐振腔中的TM₁₂₀型波间的耦合和矩形波导中的TE₁₀型波与圆柱波导中的TM_mn型波间的耦合。通过这几个问题的解法,我们希望读者可以看到处理复杂微波元件问题时所需的从物理概念出发的灵活应用已有方法的必要性。这里提供的几个公式有着广泛的应用范围而是在现有文献中探讨得不够的。这里介绍的方法可以应用到其他新的微波网络问题中去。

COUPLING BETWEEN A RECTANGULAR WAVEGUIDE AND A CIRCULAR WAVEGUIDE OR A CYLINDRICAL CAVITY THROUGH A SMALL HOLE

Three different forms of coupling through a small hole are treated by approxi mate methods, which are justified from good physical reasoning. These are the end on coupling between a rectangular and a circular waveguides, the coupling between a TE₁₀ mode in a rectangular waveguide and a TM₁₂₀ mode in a circular cavity through a circular hole in the side wall of the circular cavity and the coupling between a TE₀₁ mode in a rectangular waveguide and a TM_mn mode in circular waveguide through a circular hole in the side wall of the latter. The purpose of this paper is to demonstrate the methods of handling problems of complicated microwave component parts. A few formulas developed in this paper are believed to be new and useful in design works.
