摘要
We report the first observation of a large (more than 10%) reflectance anisotropy on a Ag(110) single crystal. We reproduce the experimental data fairly well by use of a theoretical model, based on the quasistatic approximation, which takes into account both the actual geometry of the crystal surface and the interband and intraband transitions. This demonstrates that the main effect is the screened surface local-field effect on resonant dipolar oscillations localized near the surface.
