摘要
在耦合波理论的基础上,研究了94 GHz回旋管内置TE03-TE02-TE01模式转换器和外接的TE01-TE11模式转换器。采用半径渐变微扰和轴线微扰几何结构以及不同的相位重匹配技术进行优化分析,得到了可靠的最优几何参量,设计出了紧凑、高效的94 GHz波纹波导模式转换器和蛇形线模式转换器。回旋管的热测实验中测出的模式样图表明,所设计的内置模式变换器有效地实现了TE03-TE02-TE01的模式转换。
Based on the mode coupling theory,the built-in TE03-TE02-TE01 mode converter of the 3 mm band second-harmonic complex cavity gyrotron is studied. Adopting the structure of corrugated waveguide with tapered radius and different phase rematch techniques, reliable optimal geometry parameters can be obtained. The corrugated waveguide mode converter of 94 GHz gyrotron is designed with compact structure and high efficiency, and the burned patterns measured at the ends of the converter are produced by the gyrotron and indicates good expected mode TE01.
