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...
