Magnetohydrodynamic ponderomotive forces generated about Alfv{acute e}n resonance layers

The total ponderomotive force produced by radio frequency electric and magnetic fields about the spatial resonances of the shear Alfv{acute e}n wave is derived. The time-averaged currents and plasma transport that result from these forces are also derived. The wave analysis is based on a resistive magnetohydrodynamic fluid. A relationship between the time-averaged rates of change of wave energy dissipation and wave momentum dissipation in the resonant layers is found. Since the deposited wave momentum in the Alfv{acute e}n resonant layers alters the plasma transport locally, control of the density profile is a possible application of this theory. {copyright} {ital 1996 American Institute of Physics.}
