چکیده
|
The effect of linear ion landau damping on weakly nonlinear as well as weakly dispersive low-frequency waves in a dusty plasma is investigated. the standard perturbative approach leads to the korteweg–de vries (kdv) equation with a linear landau damping term for the dynamics of the low-frequency nonlinear wave. landau damping causes the wave amplitude to decay with time and the dust charge variation enhances the damping rate. © 2017,the author(s).
