摘要: We report an oversized K-band backward wave oscillator (BWO) operating above 20 GHz in the weakly relativistic region less than 100 kV. It is very important to prevent microwave from going into beam diode, since intense microwaves will harmfully affect generation. A BWO demonstrated using a Bragg reflector at entrance of slow structure (SWS). The effect on operation examined, by changing boundary condition entrance. improves performance BWO.
