| 摘 要： | 对一种波导同轴转换器进行了数值模拟,得到了转换器的频率响应和功率容量,与实验结果相符.数值模拟表明:转换器探针的精细结构会对计算结果产生很大影响;在大功率微波注入时,微波击穿将首先发生在转换器探针的底部.

| Abstract: | Numerical simulation on a waveguide to coaxial line transformer is presented. The achieved results of frequency responses and power capacity agree with experiments. The numerical results show that the fine structure of the probe plays an important role, which may affect not only the power capacity but also the scattering parameters. When high power microwave is induced to the transformer, microwave breakdown will first occur at the end of the probe. |

| Keywords: | scattering parameters method of moment microwave breakdown |
