| 摘 要： | 给出了同轴型虚阴极振荡器的数值模拟和部分理论分析结果, 指出许多几何结构参数包括阴极宽度、二极管间隙等都对输出微波的频率、带宽和能量转换效率有较大的影响。给出了这些参量之间关系的数值模拟结果，在一定程度上为同轴虚阴极振荡器的实验研究提供了理论基础。

| Abstract: | Numerical simulations of the coaxial vircator are presented in this paper. The anode cavity provides a resonant mechanism for the interaction of beams and cavity modes. The peak output power occurred when the character impedance of transmission line matched the diode impedance, and the bandwidth of output microwave of coaxial vircator is much narrow than planar vircator. The scaling relation between impedance of coaxial diode and geometry dimensions was approximately determined by simulation results. Comparing with the positively pulsed coaxial vircator, a negatively pulsed one was higher efficiency and more narrow output microwave bandwidth. |
