Problems solved by technology

The biggest feature of the current slow-wave structure is that it is compatible with micromachining. Therefore, a high-precision, small-sized terahertz slow-wave structure can be obtained through this advanced processing method, but the problem that arises is either the problem of large high-frequency loss. , or in the vicinity of the electron beam channel, the proportion of the effective component of the electromagnetic field that can effectively interact with the electron beam is greatly reduced, that is, the coupling impedance decreases

Abstract

The invention provides a novel half-cycle staggered double-gate slow-wave structure, which comprises rectangular gates and an electron injection channel, wherein the rectangular gates are in half-cycle staggered arrangement on two wide edges of a rectangular waveguide; the electron injection channel is arranged at the center of the rectangular waveguide and runs through the rectangular waveguide along the axis direction of the rectangular waveguide; and the rectangular gates are intersected with the electron injection channel, so that the coupled impedance is improved; and the novel half-cycle staggered double-gate slow-wave structure is applicable to improvement of the gain and the efficiency of a terahertz device.

Description

technical field [0001] The invention relates to the technical field of microwave vacuum electronic devices, in particular to a novel half-period interleaved double-grid slow-wave structure. Background technique [0002] The slow wave structure is mainly used in traveling wave microwave vacuum electronic devices, and can also be used as a resonant cavity to expand the interaction standing wave device. Obtaining effective interaction between injected waves belongs to the core part of microwave vacuum electronic devices. [0003] As the frequency increases to the terahertz band, the most commonly used slow-wave structures are greatly restricted in use due to technical problems such as processing and heat dissipation. Therefore, the exploration of new slow-wave structures has received extensive attention. The biggest feature of the current slow-wave structure is that it is compatible with micromachining. Therefore, a high-precision, small-sized terahertz slow-wave structure can...
