The relativistic backward-wave oscillator (RBWO) with inner coaxial disk-loaded slow-wave structure (SWS) is studied. The dispersion relation of the SWS is deduced by using the Borgnis’s potential function method according to Maxwell’s equation and Floquet theory. Numerical analysis is carried out and the dispersion curves are gotten. The beam-wave interaction of the device is simulated and optimized by PIC method. The effect of the longitudinal magnetic field, the distance r1 between beam and SWS, the depth r2 of loaded-disk and the distance of two next disks are discussed in detail. The results show that increasing the periodic length can decrease the cut-off frequency and the operating frequency of the same mode and that the variation of the inner conductor radius almost has no effect
