Realistic Metamaterial Lenses: Limitations Imposed by Discrete Structure

Original language description

We study the peculiarities of a metamaterial "superlens," caused by its discrete structure and finite size. We show that precise modeling of the lens provides remarkable distinctions from continuous medium approximation. In particular, we address the problem of highest resolution that can be achieved with a realistic electrically thin metamaterial lens. We conclude that discrete structure imposes essential limitations on the resolution and that the resolution cannot be improved by decreasing dissipationin the system. Further implications related to effective medium description of discrete structures are discussed.
