- Abstract
- The nonthermal and harmonic-mode effects on the Buneman space charge wave are investigated in a kappa dusty plasma-filled waveguide by employing the normal mode analysis and the method of separation of variables. The growth rate and the real frequency of the Buneman space charge wave are obtained as functions of the harmonic roots of the Bessel function and the spectral index of the kappa plasma. It is shown that the growth rate of Buneman instability and the real frequency with higher-harmonic modes are smaller than those with lower-harmonic modes. It is also shown that the nonthermal effect suppresses the growth rate as well as the real frequency of the Buneman space-charge wave. The variations of the growth rate and the real frequency of the space charge wave are also discussed.
