Abstract :
The dielectric open cavity filled with the plasma is studied. The plasma density grating formed by the slow wave modulation influences the resonant parameters. Based on an equivalent model of the plasma density grating, a dispersion relation is derived and the resonant frequency, the diffraction Q value, and the field function are calculated. The field magnitude in the slow-wave region increases greatly as the plasma density increases, which can help to explain the enhancement of the beam-wave interaction efficiency
