Notes:
The dielectric tensor of a magnetized plasma described by a simple-pole particle distribution function is presented. Such model distributions give a new tool for understanding waves in collisionless non-Maxwellian plasmas. These distributions can model high-energy tails of the distribution in a way that is not possible with Maxwellians. An advantage over Lorentzian distributions is that an expression for the elements of the dielectric tensor can be obtained that does not involve any integrals over the perpendicular velocity. As an example, a simple-pole model of a magnetized space plasma is studied numerically and it is found that particle populations with the same density and mean particle energy, but with somewhat different distribution functions, correspond to different propagation properties that should be observable. © 2002 American Institute of Physics.
