In this thesis, we consider a different approach, that circumvents these limitations, in which the effective refractive index of the metamaterial is controlled by the coupling of surface plasmon polaritons (SPPs) on thin metal-dielectric-metal (MDM) waveguides. In particular, we consider a polarization-independent geometry consisting of a hexagonal array of dielectric coaxial waveguides, embedded in metal. The dispersion of the metamaterial can be controlled by tuning the geometry of the individual coaxes and designing the coupling with neighboring coaxial waveguides. In this thesis we describe the fabrication process and determine the optical properties of such a three-dimensional coaxial plasmonic metamaterial.
