通过数值模拟、制造和实验测量，设计了一种用于w波段陀螺器件的波纹角形准光模式变换器。该喇叭将84-104 GHz频段的圆柱形TE11模式转换为自由空间TEM00模式，反射优于30 dB，高斯耦合效率为98%，95 GHz时的指向性为26.6 dB。小束腰使得这样的喇叭理想的使用与一个压抑的收集器系统。实测结果与数值模拟结果吻合良好。
A quasi-optical mode converter in the form of a corrugated horn has been designed through numerical simulations, manufactured and experimentally measured for application in W-band gyro-devices. This horn converts a cylindrical TE11 mode into a free space TEM00 mode in a frequency band of 84-104 GHz with a reflection better than 30 dB, a Gaussian coupling efficiency of 98% and directivity of 26.6 dB at 95 GHz. The small beam waist makes such a horn ideal for use with a depressed collector system. The measured results are in excellent agreement with the numerical simulations.
