Abstract
We present an analytic solution for the resonant oscillations of a cold, inhomogeneous, one-dimensional plasma under the influence of a sinusoidal applied field. The model approximates the response to obliquely incident electromagnetic radiation. Energy can be absorbed collisionlessly through either electron wave breaking or ion bunching, when the driven field is strong or weak, respectively. The two regimes are distinguished by , where is the plasma scale length and the longitudinal driver. In the weak-driver case, ions with keV emergies can be produced in the resonance region.
