利用场匹配理论建立多层窗片结构输出窗的传输级联矩阵,设计出了可承受40 kW的Ku波段宽带回旋行波管双窗片结构输出窗。用三维仿真软件HFSS进行模拟,并与MATLAB数值计算结果进行比较,两者结果吻合较好。在15~17 GHz的频带内,圆形双窗片结构输出窗的反射系数小于-17.7 dB,传输系数大于S21>-0.08 dB。对实验样品的冷测实验表明:在15~17 GHz的频带内反射系数小于-17.5 dB。
Using the field matching theory, the transmission cascade matrix of the output window of a multi-layer window structure is established, and the output window of a dual-pane structure with a Ku-band broadband gyroscope capable of supporting 40 kW is designed. The simulation with HFSS software was carried out and compared with the numerical results of MATLAB. The result of the two experiments was in good agreement. In the frequency range of 15-17 GHz, the reflection coefficient of the output window of a circular double-pane structure is less than -17.7 dB and the transmission coefficient is greater than S21> -0.08 dB. The cold test on the experimental samples shows that the reflection coefficient is less than -17.5 dB in the band from 15 to 17 GHz.
