| 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, the paper proposes a gradual transitional coaxial extractor. The simulation results show that the gradual transitional coaxial extractor achieves efficient microwave extraction and a single output TEM. Additionally, the transitional coaxial structure is conductive to the design of supports, and meets TEM transmission requirement. 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. |
