Abstract

By employing standard statistical techniques of linear fluctuation theory, it is shown how the ensemble averages over statistical distributions of charged massive grains in a dusty plasma can result in "average" dispersion relations for high‐frequency electromagnetic and electrostatic waves. The dispersion relations admit solutions for complex frequencies and wave numbers, suggesting that the waves can be damped (Im ω≠0) or absorbed (Im k≠0) in a dusty plasma.
