The scattering of electromagnetic radiation in multicomponent unmagnetized plasmas with
dust particulates is considered. It is demonstrated that the effect of capture of
electrons and ions by the dust particles can affect the scattering of the electromagnetic
waves. In particular, dependence of the scattering cross
section on new parameters characterizing the charging process is found. The
expressions for static longitudinal dielectric permittivity taking into account
perturbations of the capture process are first obtained.
