Calculation of Transmission through rolled-up three dimensional Metamaterials — •Andreas Rottler, Stephan Schwaiger, Aune Koitmäe, Matthias Klingbeil, Markus Bröll, Detlef Heitmann, and Stefan Mendach — Institute of Applied Physics, University of Hamburg, Germany

Metamaterials are artificial structures where permittivity and permeability can be designed on demand and may exhibit values which are not observed in nature. In this talk, we present finite-difference time-domain simulation results on a metamaterial which consists of curved alternating layers of metal/semiconductor films. Such structures can be prepared from self-rolling strained metal/semiconductor layers and exhibit an anisotropic permittivity with tunable plasma frequency allowing for hyperlensing in the visible [1]. We performed simulations where we varied the parameters of the structure in order to optimize the transmission through the curved metamaterial.
