In this paper we present a self-consistent analysis of steady-state cu
rrent generation by nonlinear mixing of Alfven waves in a resistive in
compressible plasma slab. In the model, the low-frequency waves are ex
cited inside the plasma using external electric and magnetic current s
heet antennas; Since the plasma medium is nonlinear, the first-order p
rimary waves beat together with each other, and generate a second-orde
r steady-state longitudinal current. The steady-state current density
is computed self-consistently in the analysis using Ampere's law. Seve
ral antenna configurations and current production schemes are explored
. It is shown that it is possible to drive reasonably large steady-sta
te currents in the plasma using waves with a modest amplitude. Methods
for controlling the current characteristics by means of the antenna p
arameters are also studied. (C) 1996 American Institute of Physics.
