Metamaterials with a Dirac-like cone dispersion at the center of the Brillouin zone behave
like an isotropic and impedance-matched zero refractive index material at the Dirac-point …

Plasmonic metamaterials are artificial materials typically composed of noble metals in which
the features of photonics and electronics are linked by coupling photons to conduction …

Artificially structured metamaterials have enabled unprecedented flexibility in manipulating
electromagnetic waves and producing new functionalities, including the cloak of invisibility …

Planar metamaterials that exhibit a zero index of refraction have been realized
experimentally by several research groups. Their existence stimulated the present …

Radiation patterns and the resonance wavelength of a plasmonic antenna are significantly
influenced by its local environment, particularly its substrate. Here, we experimentally …

We fabricate and characterize a metal-dielectric nanostructure with an effective refractive
index n= 0 in the visible spectral range. Light is excited in the material at deep …

We introduce a mechanism for creating artificial high refractive index metamaterials by
exploiting the existence of subwavelength propagating modes in metallic systems. As an …

A family of coupled nanostrips with varying dimensions is demonstrated exhibiting optical
magnetic responses across the whole visible spectrum, from red to blue. We refer to such a …
