Effect of Structure Parameters on the Signal Strength in a Solid Beam Driven Plasma-Loaded Backward Wave Oscillator
The effect of structure parameters on the group velocity and signal strength of a solid beam driven plasmaloaded backward wave oscillator is investigated analytically for a particular mode. The theory of approximate cubic dispersion equation as derived earlier for a solid beam driven plasmaloaded backward wave oscillator (BWO) is used for this investigation. The effect of variation of structure parameters on the temporal and spatial growth rates and group velocity result a change in the signal strength of BWO.
Analytical Study of a Solid Beam Driven Plasma- Loaded Backward Wave Oscillator
In this paper, an analytical expression comprising linear instability phenomena leading to microwave generation in a solid beam driven plasma-loaded backward wave oscillator has been developed. This analytical treatment is a process of three-wave interaction and is based on the approximate linear theory of instability established for annular beam driven vacuum backward wave oscillator. The dispersion relation derived here is an approximate one and it can be successfully employed to study a backward wave oscillator system consisting of a sinusoidal corrugated structure having very smaller corrugation depth.
