摘要: 在模式耦合理论的基础上,详细讨论了波导轴线弯曲与波导半径渐变的圆波导模式变换,并对TE0n-TE11模式变换器的几何结构进行了优化分析,采用不同的相位重匹配技术,得到了可靠的最优几何参量。以此数据设计的8mm回旋速调管TE01-TE11模式变换器的转换效率可达98%。Abstract: Based on the theory of mode coupling, this paper discusses the circular waveguide mode conversion with waveguide axis curved and radius tapered in detail. It also carries out the optimized analysis about the geometry structure of TE0nTE11 mode converter. Adopting different phase rematch techniques, the optimal geometry parameter is obtained. The mode converter designed in this way owns high conversion efficiency exceeding 98%.
