Surface Effects on Bulk Plasmons. (Reannouncement with New AvailabilityInformation)

摘要

We discuss the effects of surfaces in bulk plasma oscillations in a metallicfilms of thickness L. The leading corrections to the plasma frequencies due to the surfaces are proportional to L to the -1. The frequencies of low-lying long wavelength modes are given by the dispersion relation of bulk modes. Resonant excitation by an external field is calculated.
