| 摘要: |
| 由于过模Ku波段高功率微波返波管通常输出TM0n混合模式，在保证较高能量转换效率的条件下，难以同时兼顾其输出模式的纯度，而辐射终端为达到理想发射效果又要求单一模式馈入，这就给输出混合模式微波源的实际应用带来了困难。针对这一技术难点，提出一种结构紧凑的TM0n-TM01（n≤3）混合模式转换器的设计方法，实现在高功率容量条件下和较宽频带范围内，高效地将TM0n混合模式转换为单一的TM01模，降低了此类高频段高功率微波源模式纯化设计的难度。 |

| Abstract: |
| Backward wave oscillator with over-mode Ku-band high power microwave (HPM) generally outputs mixed TM0n modes, it has high energy conversion efficiency, but it can′t ensure the purity of output modes. However, it is necessary for high radiation efficiency that the microwave input to the radiation terminal is certain single and pure. So it is hard to put these HPM sources into application. In order to solve this problem, a design method for compact hybrid modes converter of purifying TM0n mixed modes was proposed. With this method, the TM01,TM02 and TM03 mixed modes can be converted into pure circular waveguide TM01 mode efficiently on the condition of high power capacity and wide wave band. This method also reduces the modes purification difficulty in the design of the HPM sources. |
