摘要: 基于模式匹配法编制了分析内壁刻槽TE11-HE11圆波导模式变换器数值计算程序;采用该程序为工作频率为30.5 GHz的高功率速调管设计了一半径为16 mm的TE11-HE11模式变换器。计算表明该变换器在2.6%的带宽内转换效率在98.8%以上,实验结果表明该变换器性能良好。Abstract: A circular TE11-HE11 mode converter with slots in its inner wall is designed for a 30.5 GHz klystron using the mode matching method. Calculations show the mode converter has a conversion of higher than 98.8% inside a 2.6% bandwidth. Experiments indicate it works well. The mode matching method has advantages of minimum memory consumption, high accuracy and rapid analysis speed over the other methods.
