FIG. 1 shows the configuration of the embodiment. The electromagnetic wave matching device 1 of this embodiment includes two phase correction mirrors 3 and 5 provided in a space (vacuum state) surrounded by a vacuum wall 7, and outputs from the output window 33 of the gyrotron device 20. The millimeter wave beam having the flattened intensity distribution is converted into the HE 11 mode which is the fundamental mode of the corrugated waveguide 10 by using the phase correction mirrors 3 and 5.

Further, a plan view and a perspective view of the power distribution in the fundamental mode HE 11 of the corrugated waveguide 10 are shown in FIGS. 4 and 5, respectively.

Then, the phase is again corrected by the phase correction mirror 5, the HE 11 mode is converted, and the HE 11 mode is propagated to the corrugated waveguide 10.

得ることができるはずである。Now, it is assumed that the two phase correction mirrors 3 and 5 described above can convert a millimeter wave whose intensity distribution is flattened into a HE 11 mode millimeter wave. In this case, when the HE 11 mode millimeter wave is input to the electromagnetic wave matching device 1 from the exit of the electromagnetic wave matching device 1, that is, the entrance of the corrugated waveguide 10, the electromagnetic wave matching device 1 enters, that is, the gyrotron device 20 exits. It should be possible to obtain millimeter waves with a flat intensity distribution.

Has a complex conjugate relationship because the phase distributions in the plane crossing the traveling direction of the millimeter wave are equal and the traveling directions are opposite. That is, in all the regions including the surfaces of the two phase correction mirrors, there is a complex conjugate relationship between the input millimeter wave beam traveling in the positive direction (from the inlet to the outlet of the electromagnetic wave matching device 1) and the output millimeter wave beam traveling in the opposite direction. The phase with the millimeter wave beam with the distribution should match.

The surface shapes of the phase-correcting mirrors 3 and 5 are determined by iterative calculation so that the phases of the millimeter-wave beam and the input millimeter-wave beam match on both surfaces of the two phase-correcting mirrors 3 and 5, respectively. It would be good.
