本文介绍了利用弯曲圆波导模式转换器系统，将4GHz横磁TM 01虚阴极振荡器（vircator）模转换为线偏振TE 11模的测量结果和计算（耦合模方程）。模转换器由内径为9 cm的圆波导中曲率为39.07 cm的38.78°弯曲和曲率为25.24 cm的50.78°反向弯曲组成。在4GHz下，从TM 01到TE 11的转换效率超过90%，在3.72 ~ 4.8GHz的计算范围内，从TM 01到TE 11的总转换效率超过90%。
The measurements and calculations (coupled mode equations) on the conversion of the transverse magnetic TM01 vircator (virtual cathode oscillator) mode at 4 GHz to the linearly polarized TE11 mode are presented by means of mode converter systems using a circular waveguide with curvature. The mode converter is composed of the 38.78° bend with 39.07 cm curvature and of the 50.78° inverse bend with 25.24 cm curvature in the circular waveguide of 9 cm internal diameter. The efficiency of conversion from TM01 to TE11 at 4 GHz exceeds 90%, and the overall efficiency from TM01 to TE11 exceeds 90% in the calculated range from 3.72 to 4.8 GHz.
