两个谐振器之间的耦合将由两个谐振器的电磁场的重叠积分主导的想法很容易被许多人理解。然而，这一普遍理解直到最近一位作者根据耦合模理论[1]才得到证实。文中只给出了矩形波导或圆柱形金属屏蔽体中介质谐振器的TE模的实际计算结果[2]，因此，本文将对金属屏蔽体中的其它介质模进行补偿。按照规定的顺序，首先对每种典型的谐振器结构的积分表达式进行了简要的总结。然后，我们将继续讨论另一种重要的结构--金属谐振器，以阐明耦合的物理原理。
The notion that the coupling between two resonators will be dominated by the overlap integral of electromagnetic fields of both is easily understood by many people. This common understanding, however, has never been proved until one of the present authors did it recently based on the coupled mode theory [1]. The practical calculation was shown only for TE modes of dielectric resonators in a rectangular waveguide or circular cylindrical metal shield [2], and hence, this article will deal with the other dielectric modes in metal shields for compensation. Following the due sequence, a brief summary of formulations of integral expression are given for each typical configuration of resonators, at first. Then, we will move on to another important configuration, metal resonators, elucidating the physics of the coupling.
