| 摘 要： | 对于TM01-TE11双弯形圆波导模式转换器，在保持出射端口与入射端口轴线平行且两曲率半径相等时，通过对其轴线长度与TE11和TM01模式间拍波波长的分析，证明了在两模式间实现有效转换时，两者成正比例关系，且比例常数为2/2，并给出了相应的物理解释。通过对具体参数及模拟结果的分析，得出了模拟功率转换效率超过98%时所适用的频率下限，其值为TM01模式截止频率的1.07倍。 |

| Abstract: | The axis length and the beat-wave wavelength in double-bent circular waveguide TM01-TE11 mode converter are analyzed, keeping the axis of the output port parallel to that of the input port and keeping the two curvature radii equal. It is proved that the axis length is directly proportional to the beat wave wavelength and the ratio of the axis length to the beat-wave wavelength is 2/2. The lower limit of the pass band is obtained by theory and simulation when the simulated power conversion efficiency exceeds 98%, which is 1.07 times of that of the TM01 mode cut-off frequency. |
| Keywords: | length of axis beat-wave wavelength power conversion efficiency |
