摘　　要：为深入理解同轴虚阴极振荡器的工作原理,结合同轴虚阴极振荡器的实验结果,通过理论和数值模拟分析了同轴虚阴极振荡器微波输出模式．分析结果与在远场条件下的通过实验获得的天线辐射方向图对比．研究结果表明,同轴虚阴极振荡器输出微波由TM01模式和TE11模式共同组成,其中TM01模式所占比例约为66％- 75％,TE11模式所占比例约为25％-34％．To thoroughly understand the principle of the coaxial virtual cathode oscillator, the microwave output patterns of coaxial vircators were studied by theoretical analysis and numerical simulation. The analysis results were compared with the directional radiation diagram obtained from experiments on a far field antenna. The study shows that the microwave output patterns of a coaxial vircator are mainly composed of TM01 and TE11, and the proportion of TM01 pattern is about 66% - 75% while the proportion of TE11 pattern is abut 25% - 34%.
