Loss and gain in metamaterials

Not Accessible

Your library or personal account may give you access

Abstract

Results of studies in the influence of losses on the superresolution achievability are presented. The studies involve modeling and realization of superresolution devices. It is found that rigorous electrodynamic models that are not based on homogenization of composites can be effectively used in modeling devices with metamaterials. The possibilities to compensate losses in near-optic metamaterials by means of active inclusions or active medium are discussed and the active material design is presented. Alternatively, what we believe to be new designs are suggested for applications where losses are desirable.
