TL;DR: In this article, an extension of the fluid theory of TSWD to a warm plasma that treats boundary effects consistently is presented. But, the authors do not consider the effect of electron surface wave decay on the current density in the target.
Abstract: Two-surface wave decay (TSWD), i.e., the parametric excitation of electron surface waves, was recently proposed as an absorption mechanism in the interaction of ultrashort, intense laser pulses with solid targets. We present an extension of the fluid theory of TSWD to a warm plasma that treats boundary effects consistently. We also present test-particle simulations showing localized enhancement of electron acceleration by TSWD fields; this effect leads to a modulation of the current density entering into the target and may seed current filamentation instabilities.
