摘要: 针对现有基于特定模式成分所设计的高功率mTM0n-TEM/TM01混合模式转换器的工作原理,提出了一种大过模比结构下高功率TM0n混合模式的转换方法,可以实现将状态相对稳定且成分已知的GW量级任意模式成分比例、任意相位差的高功率TM0n混合模式微波高效转换为单一的TEM模或TM01模。利用该设计原则对之前所设计的高功率TM0n混合模式转换器进行优化改进,在保留了原有器件功率容量和频带特性的同时,大幅简化器件设计结构。Abstract: Based on the operating principle of the original high-power mTM0n-TEM/TM01 mixed mode converters, which are specially designed on the certain TM0n mode content and relative phase, the investigation on purification of high-power TM0n mixed modes is carried out in this paper. With this method, TM0n mixed modes at GW level with any mode content and relative phase can be converted into pure TEM mode or TM01 mode. The original high-power mTM0n-TEM/TM01 mixed mode converters are optimally redesigned by the method proposed in this paper, the improved mode converters not only keep the original power capacity and bandwidth property, but also have a simplified structure.
