| 摘 要： | 运用改进的"环形输运"模型和粒子模拟方法研究了调制型虚阴极振荡器中束流调制参数变化对虚阴极振荡器特性的影响。研究结果表明:束流的调制对虚阴极振荡器的运行性能有显著的影响,对电子束流进行适当的调制可以显著提高器件的束波转换效率。研究结果为设计高性能的虚阴极振荡器提供了基础。

| Abstract: | Virtual cathode oscillator (vircator) with electron beam (e-beam) modulated was studied using an improved "cellular conveyer" model and particle in cell (PIC) simulation. It is shown that the variation of the e-beam modulation parameters result in the change of vircator character, and microwave efficiency can be increased in proper e-beam modulation. |

| Keywords: | virtual cathode oscillator PIC simulation e-beam modulation |
