Abstract
The recent observation of backbending in the dispersion curves of surface plasmons on silver can be explained by use of Fresnel's equations. In the presence of damping, the results of attenuated-total-reflection measurements can be displayed as dispersion curves either with or without backbending. The measurements for silver with backbending are expected for experiments in which the frequency is fixed and the propagation constant (or angle of incidence) is swept.Keywords
