本文用严格模式匹配法研究了单膜片和双膜片圆波导腔间的耦合。单模，双模和三模耦合虹膜被认为是。可以看出，仅采用双光圈配置就可以实现和控制三模耦合。通过广义S矩阵技术进行分析;精确地考虑了频率依赖性和有限厚度，并扩展到其他类型的耦合，即，与外部输入波导的耦合是简单的。对双模和三模光阑的测量结果与计算结果吻合较好。>
Single and dual iris coupling between circular waveguide cavities is studied using a rigorous mode-matching approach. Single, dual, and triple mode coupling irises are considered. It is seen that triple mode coupling can be achieved and controlled employing only a dual iris configuration. The analysis is performed by means of the generalized S-matrix technique; frequency dependence and finite thickness are accurately taken into account, and extensions to other types of coupling, i.e., coupling to an external input waveguide are straightforward. Measured results on dual and triple mode irises show close agreement with computations. >
