The 8GHz high-power microwave device of the present invention has a very simple axial structural dimension and has the advantages of miniaturization and light weight.
Description
technical field [0001] The invention relates to an 8GHz high-power microwave device, belonging to the technical field of high-power microwave devices. Background technique [0002] High-power microwave generally refers to electromagnetic waves with peak power above 100MW and operating frequency in the range of 1-300GHz. With the development of high-power microwave research, higher and higher requirements are put forward for the total system efficiency of high-power microwave sources. [0003] The axial O-shaped high-power microwave device is a kind of high-power microwave device that is widely used due to the easy guidance of the electron beam brought by the structure and the variable combination of the structure. At present, the radiation generation of axial O-type high-power microwave devices generally requires a longer slow-wave structure to achieve synchronization of the phase velocity of the electron beam and the microwave. In the existing high-power microwave sources...
