Cross-band multifrequency controllable relativism backward-wave oscillator

Abstract

The invention discloses a cross-band multifrequency controllable relativism backward-wave oscillator. The cross-band multifrequency controllable relativism backward-wave oscillator comprises an emission cathode, a reflection chamber, a drift chamber and a leading magnetic field. An internal portion of the relativism backward-wave oscillator is provided with a coaxial inner conductor and two slow wave structures, the two slow wave structures are mutually independent and are adjustable in periods, the slow wave structures with period change and a relativism electron beam penetrating through the slow wave structures and being same as the slow wave structures in diameter realize interaction, and the slow wave structures generate multifrequency controllable L-Ku wave band high-power microwaves. Through the two slow wave period structures, the property that the coaxial structure has no cut-off frequency is utilized, and thereby the single relativism backward-wave device generates the L-Ku wave band high-power microwaves.

Description

technical field [0001] The invention belongs to the technical field of high-power microwave devices, and in particular relates to a cross-band multi-frequency controllable relativistic return wave oscillator. Background technique [0002] In order to cope with complex frequency-using equipment, multi-frequency controllable high-power microwave devices have become a core component that urgently needs to be studied. The formation of this type of device is a potential application scenario proposed as high-power microwave technology gradually becomes practical. Implement countermeasures. The working process of the multi-frequency controllable high-power microwave device is as follows: under each pulse voltage, the device can sequentially radiate and generate high-power microwaves of different frequencies by adjusting the structural parameters. Each frequency point can be generated according to certain rules by preset, and each frequency point Generate independently in a certain...

Problems solved by technology

From the above calculations, it can be seen that due to the strong correlation between the period of the slow wave structure and the frequency, simply adjusting a section of the slow wave structure cannot realize the high-power microwave generation of the relativistic return wave oscillator in the L-Ku band.
