| contents | We consider light propagation in a silicon dioxide substrate with implanted ${\mathrm{Er}}^{3+}$ ions and silver nanoparticles that are randomly and homogeneously distributed in the substrate. When their densities are large enough, the medium can have a negative refractive index over a certain range of frequencies, within which the following exotic property ensues: increasing the electric and magnetic plasma frequencies, the medium transparency is augmented. |
