| Abstract: | An X-band large diameter coaxial relativistic backward wave aseillator (CRBWO) was prasented and designed in the paper. The complete dispersion relation and coupling impedance of TMon mode in the coaxial corrugated cylindrical waveguide used in the CRBWO were analyzed and calculated by FDTD method. An electromannetic particle-in-cell codeis being used to investigate the nonlinear beam wave interaction and perfonnance optimization issues of the device. The simulation results show that the CRBWO can generate GW level microwve power at X-band frequency very efficiently. |
