摘要
We investigate the excitation of electrostatic wake fields in metallic nanostructures (nanowires) due to the propagation of a short electron pulse. For that purpose, a dispersive (nonlocal) dielectric response of the system is considered, accounting for the conning along the transverse direction of the wire, which generalizes previous results presented in the literature. We discuss the stability conditions of wake fields and show that the underling mechanism can be useful to investigate new sources of radiation in the extreme-ultraviolet range.
