Description
Summary: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.
