Metamaterial dielectric resonators represent a promising path toward low-loss metamaterials at optical frequencies. In this paper we utilize perturbations of high symmetry resonator geometries, such as cubes, either to overlap the electric and magnetic dipole resonances, thereby enabling directional scattering and Huygens' metasurfaces, or to induce couplings between the otherwise orthogonal resonator...
We use phase-locked time-domain spectroscopy in the mid-infrared to directly demonstrate the “infrared magnetic mirror” behavior of an all-dielectric metamaterial. This metamaterial surface consists of micron-sized cubes of tellurium fabricated on a dielectric substrate.
