摘要

对一种用于回旋管行波放大器的内表面光滑的w波段准光学角进行了优化和测量。在90至100 GHz的期望频率范围内实现低反射、高基态高斯模含量和高指向性。在测量中，TE11模式的反射小于−37 dB，指向性为~ 27 dB，侧瓣优于−30 dB。

Smoothly profiled quasi-optical output launcher for a W-band gyro-TWA

A W-band quasi-optical horn with smoothly profiled circular inner surface was optimized and measured for a gyrotron traveling wave amplifier. It was designed to achieve low reflection, high fundamental Gaussian mode content and high directivity in the desired frequency range of 90 to 100 GHz. In the measurement, the reflection of the TE11 mode was lower than −37 dB and the directivity was ∼27 dB with side lobes better than −30 dB.
