Abstract
Since decades, scientists were interested in the fundamental mechanisms of light matter interaction. In 1999 Pendry et al. described a material system with dimensions shorter than the impinging wavelength which showed a negative index of refraction [1]. Because of the given opportunity of artificially designing the interaction response of these new structures, the research interest in this new field of metamaterials has increased ever since. With the proper design, transmission and refraction properties can be controlled [2], even leading to a perfect lens [3]. In the last years, it was possible to use them as plasmonic resonators in order to rotate the polarization of the electric field and fulfill the quantum mechanical selection rules to access intersubband transitions in quantum heterostructures [4].
