摘要

采用双交错光栅(DSG)慢波结构(SWS)和伪火花源片状电子束设计了双频倒向波振荡器(BWO)。在高频特性仿真中，DSG SWS显示出72 ~ 125 GHz的宽工作频带和高耦合阻抗。BWO的完整结构由10个DSG SWS单元和一个宽带输出结构组成。在DSG BWO的冷试验仿真中，在74 ~ 100ghz和109 ~ 125ghz频段的传输均大于−7db。通过粒子池(PIC)仿真分析了DSG BWO的热测试性能，显示了75-100 GHz (25 GHz带宽)和108-115 GHz (7 GHz带宽)的双频工作，具有高输出功率(最大输出功率)。162千瓦)。

Design of Dual-Band High-Power Backward Wave Oscillator using Double Staggered Grating and Pseudospark-Sourced Sheet Beam

We have designed a dual-band backward wave oscillator (BWO) using a double staggered grating (DSG) slow-wave structure (SWS) and a pseudospark-sourced sheet electron beam. In the simulation of the high-frequency characteristics, the DSG SWS has been shown a wide operating band of 72–125 GHz and a high coupling impedance. The complete structure of the BWO consists of 10 DSG SWS units, together with a wideband output structure. In the cold-test simulation of the DSG BWO, the transmission is greater than −7 dB in the band 74–100 GHz, and 109–125 GHz. The hot-test performance of the DSG BWO is analysed by particle-in-cell (PIC) simulation, showing dual-band operation in 75–100 GHz (25-GHz bandwidth) and 108–115 GHz (7-GHz bandwidth), with high output power (max. 162 kW).
