2On the dynamics of nonlinear propagation and interaction of the modified KP solitons in multicomponent complex plasmas显示文摘Dust-acoustic waves(DAWs)are analyzed in the small amplitude limit in a collisionless unmagnetized dusty plasma whose constituents are inertial dust grains,massless ions expressed by the generalized(r,q)distribution and inertialess Maxwellian electrons using the fluid theory of plasmas.The modified Kadomtsev-Petviashvili(mKP)equation is derived at a critical plasma condition for which the quadratic nonlinearity vanishes.The propagation of single soliton and interaction of two solitons are analyzed for the mKP equation in the context of plasma physics by employing Hirota bilinear formalism.The effects of the flatness parameter rand tail parameter q of the ions on the frequency of the DAWs are studied and the comparison with Maxwellian and kappa distributions is drawn.Using the plasma parameters corresponding to the Saturn’s E-ring,the range of electric field amplitude for dust-acoustic solitary waves(DASWs)for different ion distributions is calculated and is shown to agree very well with the Cassini Wideband Receiver(WBR)observations.The interaction time of two DASWs for non-Maxwellian ion distributions is estimated and shown to be fastest for the(r,q)distributed ions.The interesting feature of the interaction between compressive solitons with their rarefactive counterparts is also discussed in detail.Muhammad Shohaib W.Masood R.Jahangir M.Siddiq Sadah A.Alkhateeb S.A.El-Tantawy 2022Journal of Ocean Engineering and Science2022,7,6:0
