A dispersion relation for a multi-component high-degenerate plasma is investigated by applying the RPA to an idealised system in which carriers are assumed to be free charged particles with isotropic effective mass. The dispersion relation is expanded up to the sixth-order terms in the wave vector and the frequencies of optical and acoustic plasma modes are calculated.
