发布时间：2019-03-21 15:39
【摘要】：通过理论和数值模拟方法,考虑金属粗糙度的情况下,研究了加工垂直度公差角在0~6°范围内变化时折叠波导慢波结构的工作性能,结果表明:金属波导表面的粗糙度增大时,慢波结构中电磁信号的传输损耗增大;垂直度公差角的增大也使得电磁信号的传输损耗增加,而且垂直度公差角所引起的结构变化会引起器件的电压工作点漂移、带宽降低等。
[Abstract]:By means of the theory and the numerical simulation method, the working performance of the folded waveguide slow-wave structure is studied in the range of 0-6 掳 by considering the metal roughness, and the results show that when the roughness of the surface of the metal waveguide is increased, The transmission loss of the electromagnetic signal in the slow-wave structure is increased, the increase of the vertical tolerance angle also increases the transmission loss of the electromagnetic signal, and the structural change caused by the vertical tolerance angle can cause the voltage working point of the device to drift, the bandwidth is reduced, and the like.
