Multi-dimensional instability of dust-ion-acoustic solitary structure with opposite polarity ions and non-thermal electrons

An attempt has been made to study the multidimensional instability of dust-ion-acoustic (dia) solitary waves (sws) in magnetized multi-ion plasmas containing opposite polarity ions, opposite polarity dusts and nonthermal electrons. first of all, we have derived zakharov-kuznetsov (zk) equation to study the dia sws in this case using reductive perturbation method as well as its solution. small-k perturbation technique was employed to find out the instability criterion and growth rate of such a wave which can give a guideline in understanding the space and laboratory plasmas, situated in the d-region of the earth’s ionosphere, mesosphere, and solar photosphere, as well as the microelectronics plasma processing reactors.
