Nano-CNC fabricating Y-band folded waveguide backward wave oscillator

We present simulation results on a Y-band folded waveguide backward wave oscillator (BWO). Since the finalized circuit will be fabricated by nano-computer numerical control machining, we obtained its parameters from analytic equations with considering cutting tool's dimensions. Depending on the different number of periods, BWO's generated frequency and power were obtained. A cold test and hot test of the circuit is discussed in simulation level.
