| 摘 要： | 综合两种现有磁绝缘线振荡器的优点，对器件进行改进，将双渐变结构、轭流片和阻抗渐变三种增大功率的机制综合考虑，利用二维半全电磁PIC程序进行数值模拟，设计了一种新的改进型磁绝缘线振荡器，当外加电压为550kV，电流为35kA左右时，在L波段获得了6GW的峰值输出功率。

| Abstract: | With the combination of three gain mechanism of double tapered structure, choke and impedance transition based on the two present magnetically insulated transmission line oscillater (MILO) models, a new improved type MILO has been designed through numerical simulation using two and a half dimensional particle-in-cell (PIC) code. Its peak output power is 6GW in L band when input voltage is 550kV and input current is about 35kA. |
