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...
