Some electrostatic modes based on non-Maxwellian distribution functions
View through CrossRef
A comparative study of fundamental modes such as Langmuir waves, dust ion acoustic waves, and dust-acoustic waves using non-Maxwellian distribution functions is presented. The real frequency and the growth rate of the modes are calculated by using kappa and generalized (r,q) distribution functions and results are compared with those of Maxwellian distribution. It is noted that in the limit (i) r=0, q→∞ for generalized (r,q) distributions and (ii) κ→∞ for kappa distributions, the non-Maxwellian functions reduce to Maxwellian.
