报告简介:The field of metamaterials has seen spectacular progress. Most metamaterials have a metal-based nanostructure and eventually suffer from conductor losses at optical frequencies, which are still orders of magnitude too large for realistic applications. In addition, metamaterials’ losses become an increasingly important issue when moving from multiple metal-based metamaterial layers to the bulk case. Thus, the need for reducing or even compensating for the losses is a key challenge for metamaterials’ technologies. One promising way of overcoming the losses is based on introducing the gain material to the metamaterial.In this talk, we will present a self-consistent model incorporating the gain into a dispersive metamaterialnanostructurea and systematic theoretical model for pump-probe experiments of metallic metamaterials coupled with the gain material, described by a generic four-level atomic system.
