Resumen:
We investigate the excitation of plasmons by a fast charged particle moving in the vicinity or traversing the surface of a solidalong an arbitrary trajectory. We use both quantum-mechanical and semiclassical dielectric formulations to study how theparticle couples with the bulk and surface excitations. We pay special attention to the differences and similarities betweenincoming and outgoing trajectories, finding some novel oscillatory structures that can be ascribed to an interference effectbetween direct and reflected plasmon excitations.
