Properties of Damped Cylindrical Solitons in Nonextensive Plasmas

Abstract

Abstract Wave properties of damped solitons in a collisional unmagnetised four-component dusty fluid plasma system containing nonextensive distributed electrons, mobile ions and negative-positive dusty grains have been examined. The reductive perturbation (RP) analysis is used under convenient geometrical coordinate transformation; we have derived three-dimensional damped Kadomtsev-Petviashvili (3D-CDKP) equation to study dissipative dust ion acoustic (DIA) mode properties. It is found that the properties of damped cylindrical solitons in nonextensive plasmas in cylindrical coordinates are obtained. The effects of collisional parameters on damped soliton pulse structures are studied. More specifically, the cylindrical geometry with the time on solitary propagation is examined. This investigation may be viable in plasmas of Earth’s mesosphere.
