Waves in Warm Quiescent Plasmas
Journal Article

· Canadian Journal of Physics
The comparison is made between the analyses of waves in a plasma which use perturbation theory, the Cartesian tensor or spherical harmonic expansion, and the integrated velocity moment equations. When the wave phase velocities are much greater than the average particle thermal velocities and when collision frequency is independent of velocity, then to first order in thermai transport terms, the three approaches give the same answer for plane waves, except for the phenomenon of Landau damping. Neglecting such damping and remembering the restriction on phase velocity, the use of integrated moment equations can then be justified in attacking non-planar wave problems. First-order relativistic effects are also considered.
