| 摘要: |
| 同轴插板式模式转换器是一种新型高功率微波TEM-TE11模式转换器。回顾了模式转换器中的模式转换过程，通过分析不同模式转换过程中波导不连续性结构的反射特性，得到了模式转换器总的反射特性。指出不连续性结构将在输入口形成同轴TEM和同轴TE11反射模；通过选择模式转换器的内外径尺寸可以消除TE11反射模；通过在输入口引入匹配金属杆和合理设计内导体末端锥体结构可以减小TEM反射模。 |

| Abstract: |
| The coaxial plate-inserted mode converter is a novel high-power microwave TEM-TE11mode converter. The mode conversion processes of the mode converter were reviewed, and the reflective characteristics were studied by analyzing the waveguide discontinuousness. It is revealed that, the reflection modes of the mode converter are TEM mode and TE11mode, the reflection TE11 mode can be canceled by choosing the right radii of the coaxial waveguide, and the reflection TEM mode can be diminished by setting matching poles and properly designing the cone at the end of inner conductor. |
