Abstract: This paper contains results of analytical investigation of a solid beam driven plasma loaded backward wave oscillator. Here, an instability leading to microwave generation involves a process of three-wave interaction. The theory of approximate cubic dispersion equation valid near resonance for annular beam driven vacuum backward wave oscillator (BWO), was derived earlier. In this paper, by extending and modifying this theory is used for investigating the effect of variation of SWS size parameters on the oscillation frequency and growth rates for solid beam driven plasma loaded BWO.
