Oblique propagation of nonlinear ion-acoustic cnoidal waves in magnetized electron–positron–ion plasmas with nonextensive electrons

引用

Plasma Science and Technology 2021年第3期23卷 76-81页

作者： muhammad KHALID Ghufran ULLAH Mohsin KHAN sheraz AHMAD Sardar NABI Daud KHAN Depatment of Physics Govermment Post Gaduate College MardanMardan 23200Pakistan Department of Physics Islamia College Peshawar(Public Sector University)Peshawar 25120Pakistan Department of Physics Government Post Graduate College NowsheraNowshera 24100Pakistan

Theoretical investigation of nonlinear electrostatic ion-acoustic cnoidal waves(IACWs) is presented in magnetized electron–positron–ion plasma with nonextensive electrons and Maxwellian positrons. Using reductive perturbation technique, Korteweg–de Vries equation is derived and its cnoidal wave solution is analyzed. For given plasma parameters, our model supports only positive potential(compressive) IACW structures. The effect of relevant plasma parameters(viz., nonextensive parameter q, positron concentration p, temperature ratio σ,obliqueness l3) on the characteristics of IACWs is discussed in detail.
