| 摘 要： | 用数值计算的方法计算了S波段磁绝缘线振荡器（S-MILO）的主慢波结构谐振腔的π/4模、π/2模、3π/4模和π模的谐振频率，分别为1.40，2.21，2.46和2.51 GHz；计算出S-MILO封闭腔中的谐振频率依次为1.26，2.04，2.42和2.53 GHz，并计算了本征π模时的Q值。通过监测宽带激励源响应计算出S-MILO开放腔的谐振频率为2.43 GHz。对S-MILO开放腔传输特性研究表明：频率为2.25～3.05 GHz的微波，在第一腔内得到了有效抑制，输出微波的频率范围为2.2～2.5 GHz。通过对其传输特性进行研究，验证了S-MILO的高频电磁结构的合理设计。

| Abstract: | Through numerical calculation, S-band magnetically insulated line oscillator (S-MILO) is calculated. The frequencies of the π/4, π/2, 3π/4 and π mode of primary coaxial slow wave structure (SWS) cavity calculated in the simulation are 1.40, 2.21, 2.46 and 2.51 GHz, respectrively. The frequencies of corresponding modes of the S-MILO closed cavity are 1.26, 2.04, 2.42 and 2.53 GHz. The quality-factor of π mode is also calculated. The eigen-frequency of S-MILO open cavity is 2.43 GHz by calculation, the frequency from 2.25 to 3.05 GHz is cut off in the RF choke, the output frequency is from 2.2 to 2.5 GHz. The results indicate that the high frequency structure of the S-MILO is reasonable. |
