Solitons and Resonant Absorption

Abstract

Simulations and theory of driven plasmas show the existence of long-lived, extremely intense spikes of high-frequency electric field, accompanied by a self-consistent depression in density. These entities are the limit to which solitons collapse in a driven plasma when the wave-particle interaction is included. Alterations in the density profile due to such entities is especially important for the absorption of radiation in inhomogeneous plasmas.
