Nonthermal effects on the resonant instability of the dust-acoustic wave in a semi-bounded Lorentzian dusty plasma

The nonthermal effects on the resonant instability of the surface dust-acoustic wave are investigated in a semi-bounded Lorentzian dusty plasma containing elongated rotating dust grains. It is found that the nonthermal effects reduce the frequency domain and enhance the growth rate of the resonant instability for the case of positively charged dust grains. For negatively charged dust grains, however, the nonthermal effects on the frequency domain and the growth rate are found to be negligible. It is also found that the growth rates of the resonant instabilities in nonthermal plasmas would be greater than those in thermal plasmas.
