| 摘要: |
| 提出了一种渐变过渡型的微波同轴提取结构，解决了采用传统的均匀同轴提取结构的Ku波段磁绝缘线振荡器中存在的输出模式不纯和TEM模传输效率较低的问题。模拟结果表明，渐变过渡型提取结构实现了微波的高效提取和单一的同轴TEM模输出；过渡后的同轴结构利于支撑杆的设计，满足了同轴TEM模的传输要求。与传统的均匀同轴提取结构相比，渐变过渡型提取结构能够适量提高器件的品质因数，进而加强束波作用，加快微波起振。 |

| Abstract: |
| To solve the problems of impure output modes and inefficient TEM transmission in the Ku-band MILO with the conventional uniform coaxial extractor, a gradual transitional coaxial extractor was proposed. The simulation results show that: the gradual transitional coaxial extractor achieves efficient microwave extraction and a single output TEM; the transitional coaxial structure is conductive to the design of supports and meets TEM transmission requirements. Compared with the traditional extractor, the gradual transitional coaxial extractor can strengthen the beam-wave interaction and accelerate the microwave start-up through enhancing the quality factor of the Ku-band MILO in right amount. |
