Problems solved by technology
This frequency adjustable technology requires the pulse power source to have a large voltage adjustment range, but when the device outputs high-power microwaves, the electron beam speed in the device is close to the speed of light, so it is very insensitive to voltage changes, and the general pulse source also only provide limited voltage regulation capability

Embodiment Construction
[0025] Such as figure 1 , figure 2 , image 3 As shown, an adjustable slow-wave structure plate-loaded waveguide microwave device device of the present invention includes an outer circular waveguide, a screw arranged in the outer circular waveguide and several slow-wave structure disks, and the several slow-wave structure disks Coaxial with the outer circular waveguide, the screw is arranged between the slow wave structure disk and the outer circular waveguide, and the screw is parallel to the axis of the outer circular waveguide.
[0026] In the actual operation process, the outer circular waveguide is cut along the axial direction to facilitate the installation of the screw and the slow wave structure disc. The number of slow-wave structure discs and the thread pitch on the threaded rod need to be designed in advance. The slow-wave structure discs adopt a cylindrical shape. The outer surface of the cylinder protrudes a circle of connecting parts, and a threaded hole is p...

Description
technical field [0001] The patent of the present invention relates to the technical field of high-power microwave devices, in particular to an adjustable slow-wave structure plate-loaded waveguide microwave device device. Background technique [0002] In the microwave device technology using the plate-charged waveguide as the slow wave structure, in order to realize the adjustable output frequency of the device, the output microwave frequency of the microwave device is generally changed by adjusting the input microwave device voltage and current. This frequency adjustable technology requires the pulse power source to have a large voltage adjustment range, but when the device outputs high-power microwaves, the electron beam speed in the device is close to the speed of light, so it is very insensitive to voltage changes, and the general pulse source It also only provides limited voltage regulation capability. In a relativistic high-power microwave device using a disk-loaded w...
