使用非麦克斯韦分布函数对朗缪尔波、尘埃离子声波和尘埃声波等基本模式进行了比较研究。利用kappa和广义(r,q)分布函数计算了模态的真实频率和增长率,并将结果与​​麦克斯韦分布的结果进行了比较。值得注意的是,在极限 (i) r=0、广义 (r,q) 分布的 q→∞ 和 (ii) kappa 分布的 κ→Infini 下,非麦克斯韦函数简化为麦克斯韦函数。
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.
