示す電界分布となるので、モード結合となる。As in the embodiment shown in FIG. 3, when the first and second cavity resonators 5 and 6 are coupled through the coupling window 9, the size of the coupling window is selected as follows. This results in mode coupling. That is, the first cavity resonator 5 is TMQ2. When excited in this mode, the electric field distribution El shown in FIG. 7 is obtained. When the zero point of the electric field becomes the wall surface and forms a window 9 with a size between the positive or negative extreme values of the electric field, the second cavity resonator 6 has a wall surface that Since the electric field distribution E2 is similar to the electric field distribution E1, mode coupling occurs.

ある。The size of this second cavity resonator 6 is also selected so that the zero point of the electric field is on the wall surface. Such a configuration has the advantage that the coupling between the first cavity resonator 5 and the second cavity resonator 6 is large and unnecessary modes are less likely to occur. Therefore, it becomes possible to stably distribute or combine ultra-high frequency power. Note that the present invention is not limited to the above-mentioned modes, and can also be applied to other modes.
