Simulation study of resonant reflector for S-band BWO

This paper presents the result of simulation studies of resonant reflector used for reflection of backward wave in relativistic BWO. The resonant reflector is modelled and analyzed by CST MWS for TM01. A TM01 mode is fed at the output end of the BWO and signal is observed at the cathode end. Results show that 90 percent of the backward TM01 wave is get reflected back by the locked TM02 mode in the resonant reflector.
