Vy. Bychenkov et al., TRANSVERSE ELECTRON SUSCEPTIBILITY AND THE ELECTROMAGNETIC-WAVE ABSORPTION IN WEAKLY COLLISIONAL PLASMAS, Physics of plasmas, 4(12), 1997, pp. 4205-4209
A theory of plasma response to electromagnetic perturbations has been
developed based on the full solution to the Fokker-Planck equation in
high Z plasmas without electron-electron collisions. For the first tim
e the transverse electron susceptibility has been calculated for the e
ntire range of frequencies and wave numbers including the quantitative
description of the weakly collisional regime where the wave frequency
is comparable to the electron-ion collision frequency and the wave nu
mber is comparable to the inverse electron mean free path. The results
have been compared to approximate expressions for the electron conduc
tivity based on the Drude model showing discrepancy by a factor of few
in regions where the spatial dispersion is important. The theory is a
pplied to the calculation of laser light absorption in solid density p
lasmas. (C) 1997 American Institute of Physics.
