| 摘 要： | 为进一步提高虚阴极振荡器输出微波的功率和效率,同时为使其输出微波的频率更加稳定、模式更加单纯,设计了一种轴向提取的反馈式虚阴极振荡器,并利用粒子模拟方法分析了反馈装置对输出微波的影响,得到了一些规律性的认识。模拟结果表明,在相同的运行条件下,与不加反馈装置时的普通虚阴极振荡器相比,这种反馈式虚阴极振荡器的微波输出功率可以提高两倍以上,而且带宽窄、模式纯。

| Abstract: | An axially extracted virtual cathode oscillator(vircator) with a feedback annulus is configured through particle-in-cell(PIC) simulation. And the effects of the feedback mechanism are studied through PIC method. The simulation results indicate that the new vircator can increase the output power more than two times compared with the conventional axially extracted vircator under the same condition. Besides it can narrow the bandwidth and purify the modes. |
