Metallic nanostructures are suitable building blocks for optics on a
subwavelength scale. Plasmonic resonances in these nanostructures allow for
tailoring the interaction between light and matter. Combining suitable
shapes with resonant excitation will lead to novel functionalities,
including negative permeability as well as negative permeability at optical
frequencies. Stacking of several layers (see picture below) adds an
additional degree of freedom and is considered the pathway towards bulk
negative refractive index materials [1]. Metallic nanostructures can also
serve as suitable nanoantennas, fostering the coupling to light emitting
constitutents.
