Abstract:

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 thermal 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 of phase velocity, the integrated moment equations can then be used to attack non-planar wave problems, such as the interaction of a finite electron beam with a finite plasma. First-order relativistic effects are also considered. Author
