Electrical Conductivity of Magnetoplasmas

Résumé du livre

The use of effective parameters to take into account the velocity dependence of the electron neutral collision frequency is reviewed. The concept of an effective collision frequency and an effective plasma frequency is applied to wave propagation in weakly ionized magnetoplasmas. The relationship between these effective parameters and a new collisional response function R(y) is described. Curves are presented of the effective parameters as a function of frequency for both a pure power law dependence of the collision frequency on electron velocity and for the case of a coupling between two power law variations. The isotropic part of the electron distribution is taken to be Maxwellian. (Author).
