✦ Synopsis

Results of studies in the influence of losses on the superresolution achieveability 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 are discussed; they appear to be rather doubtful. Alternatively, new designs are suggested for applications where losses are desirable.
