On the local power dissipation of h.f. waves in hot inhomogeneous plasmas

摘要: In a medium with spatial dispersion the power Pabs dissipated per unit volume by an electro-magnetic wave differs from (J.E) divergence of vector which is interpreted as correction delta Skin to Poynting flux due coherent particle motion in field. The authors obtain expressions for and hot, inhomogeneous, weakly collisional plasmas evaluating time-averaged rate change total kinetic energy density charged particles, generalizing method suggested McVey et al. (Phys. Rev. Lett. vol.55, p.507, 1985). prove that these are consistent time averaged theorem Maxwell equations. By specializing them uniform plane-stratified geometries, they derive some interesting properties wave-plasma exchanges, check well known case plane propagating infinite homogeneous plasma recovered appropriate limit.
