| Abstract: | An C-band and X-band dual-frequency coaxial relativistic backward-wave oscillator (CRBWO) with a
resonant reflector and a single annular electron beam is designed and investigated with 2.5-D particle-in-cell (PIC) simulation
code in this paper. The PIC simulation results indicate that, with an electron beam of 510 kV and 9.03 kA guided by an axial
magnetic field of 0.73 T, an average power of 0.95 GW with power conversion efficiency of 20.6% is obtained and the two
dominant frequencies are 8.1 GHz and 9.9 GHz, respectively. The efficiency is higher than dual-band non-coaxial RBWO and
dual-band magnetically insulated line oscillator. |
