Abstract

We investigate a symmetric layered structure that consists of a slab containing Lorentz oscillators bounded on both sides by thin metal films. We show that the absorption and the dispersion introduced by the Lorentz oscillators can drastically affect the coupled surface plasmon resonances, leading to a suppression or shift of the resonances. The frequency dependence of the reflectivity can show a splitting for larger densities of oscillators. The splitting is explained in terms of backbending in the dispersion of the long- and the short-range modes and their overlap because of resonance broadening.
