متن کاملNear-infrared double negative metamaterials.
We numerically demonstrate a metamaterial with both negative epsilon and negative mu over an overlapping near-infrared wavelength range resulting in a low loss negative-index material. Parametric studies optimizing this negative index are presented. This structure can be easily fabricated with standard semiconductor processing techniques.
متن کاملRealization of mid-infrared graphene hyperbolic metamaterials
While metal is the most common conducting constituent element in the fabrication of metamaterials, graphene provides another useful building block, that is, a truly two-dimensional conducting sheet whose conductivity can be controlled by doping. Here we report the experimental realization of a multilayer structure of alternating graphene and Al2O3 layers, a structure similar to the metal-dielec...
متن کاملDynamic Manipulation of Infrared Radiation with MEMS Metamaterials
The advent of metamaterials has ushered in a new era of designer electromagnetic materials and has realized novel responses ranging from negative refractive index [ 1–4 ] and superlensing [ 7 ] to perfect absorption [ 8,9 ] and cloaking. [ 5,6 ] Metamaterials are fashioned from ‘artifi cial atoms’, which are engineered to yield a specifi c response to the electric and magnetic components of lig...
متن کاملNear-infrared surface plasmon polariton dispersion control with hyperbolic metamaterials.
We demonstrate experimentally signatures and dispersion control of surface plasmon polaritons from 1 to 1.8 µm using periodic multilayer metallo-dielectric hyperbolic metamaterials. The fabricated structures are comprised of smooth films with very low metal filling factor. The measured dispersion properties of these hyperbolic metamaterials agree well with calculations using transfer matrix, fi...
