【摘要】 在模式耦合理论的基础上,采用相位重匹配技术,对8mm蛇形线圆波导TE₀₁-TE₁₁模式变换器的几何结构进行了优化分析,得到了最优几何参量。将数值计算得到的TE₁₁模式转换效率带宽与HFSS仿真软件得到的结果做了进一步比较,两者基本吻合。设计的模式变换器的转换效率达98.2%,带宽超过8%。更多还原

【Abstract】 Based on the mode coupling theory and by numerical solution of the coupled waves equations,an 8mm TE₀₁-TE₁₁ mode converter geometry configuration with traditional snake-like curvature and improved waveguide axis geometry period perturbation is designed for more acceptable geometry parameters.Numerical calculations indicate that the mode converter has advantages over the traditional one in short length and transmission efficiency.Comparison between numerical calculation and HFSS simulation shows that conversion efficiency of the high-power circular waveguide mode converter is over 98.2%with bandwidth of 8%.更多还原
