为了满足人们对高功率（101 -200 W）THz源日益增长的兴趣，我们的研究小组一直在研究各种技术，以使真空电子器件在保持高功率水平的同时，提供宽的瞬时带宽操作。我们已经制造了两种不同的0.22太赫兹电路结构的设计，包括输入/输出耦合器WR 4波导。我们使用纳米CNC铣削作为主要方法，能够实现出色的表面光洁度，并满足高频宽带宽行波管电路的高公差要求。
To satisfy the growing interest in high power (∼1–200 W) THz sources, our research group has been working on various technologies to miniaturize vacuum electronic devices while keeping the power levels high and offering wide instantaneous bandwidth operation. We have manufactured two different designs of 0.22 THz circuit structures including input/output couplers to WR4 waveguide. We have used nano CNC milling as our primary approach and we were able to achieve excellent surface finish and meet the high tolerance requirements of the high frequency wide bandwidth traveling wave tube circuit.
