We experimentally demonstrate a dielectric metamaterial comprising silicon nanofins on a glass substrate. Left- and right-circularly polarized beams incident upon the device are deflected into different directions. Our approach avoids the efficiency issues of plasmonics.
We investigate resonant enhancement of light in transition metamaterialsunder the local and nonlocal response function approximations, and analyze the influence of nonlocality on the field distribution in the near-zero region.
We report a broadband terahertz metamaterial absorber with two nested back-to-back split-ring resonators constituting a single planar resonator. Bandwidths of 0.66THz and 0.98THz with the absorptivity above 0.8 and 0.6 were experimentally obtained respectively.
We argue that the metamaterial approach to dielectric response engineering may considerably increase the critical superconducting temperature of a composite superconductor-dielectric metamaterial.
We demonstrate a new class of metamaterials with dielectric meta-atoms coupled to the incident waves by nonresonant metallic antennas. The storage of energy in the dielectric enables high-quality resonances in negative-permittivity and negative-permeability sheet metamaterials.
We demonstrate that nonlocal nanowire metamaterials can help to alleviate one of the main limitations of Salisbury screens, their dependence on the incident angle.
We introduce a new “universality class” of artificial optical media - photonic hypercrystals. These hyperbolic metamaterials with periodic spatial variation of dielectric permittivity on subwavelength scale, combine the features of optical metamaterials and photonic crystals.
