Abstract |
|
|
| We report in this work the study of the permittivity and the losses in non-linear nonmagnetic negative refractive index media. We analyze the permittivity and the losses dependence on the inclusion number of the particles used in the suggested media that is made by interlacing plasmonic metallic particles and a dielectric. We show that the exhibition of a negative permittivity in these strongly anisotropic media depends not only on the inclusion number of the particles and the frequency range but also on the oscillation frequency of free electrons in the metal which plays the major role. We finally suggest the use of supraconductor nanoparticles in the design of metal dielectric structures as a very promising route to create metamaterials, mainly in Chalcogenide glass as they provide low losses, high quality with non-linearity in fabrication.
