The growth rate and the real frequency are calculated by using kappa (k) and generalized (r, q) distribution and result are compared with those of Maxwellian distribution. In an electrons-ions plasma following a non-Maxwellian generalized distribution function kappa (k) and (r, q), as shown a kinetic instability of ion-acoustic mode exist. In a three species (electrons, ions, dust) plasma following a non-Maxwellian generalized kappa (k) and (r, q) distribution function, as shown that a kinetic instability of dust-acoustic mode exists.enDepartment of PhysicsSp19NATURAL SCIENCES::PhysicsSolar Wind Driven Kinetic Instability In TheThesis
