technical field [0001] The invention relates to a microwave source device in the technical field of high-power microwaves, in particular to a millimeter-wave band transit time oscillator based on a high-order mode working mechanism, and belongs to the technical field of high-power microwaves. Background technique [0002] High-power microwave usually refers to electromagnetic waves with a peak power greater than 100MW and a frequency between 1 and 300GHz. It has been widely used in many national defense and industrial fields such as directed energy weapons, radar satellites, electronic high-energy radio frequency accelerators, remote sensing and radiation measurement. [0003] The high-power microwave source is the core component for generating high-power microwave radiation. It uses the interaction between the high-current electron beam and the resonant cavity to generate high-power microwave. Transit-time oscillators use high-current electron beams to exchange energy with ...

AI Technical Summary

Problems solved by technology

[0007] It can be seen from the above that the L-band transit time oscillator has the advantages of simple structure and high output efficiency, but in the millimeter wave band, due to the reduction in size of the transit time oscillator, the power capacity is limited, and the surface field strength in the device is relatively large. , there is a risk of breakdown

At present, there is no relevant research on high-frequency transit-time oscillators, especially the technical solutions of millimeter-wave transit-time oscillators that simultaneously achieve high conversion efficiency and high power capacity have not yet been publicly reported.
