Furthermore, it is found out that negative refractive index, permeability and permittivity are dependent upon the width of the wire and the gap between resonators at near-infrared range. This work will be helpful for the fabrication and design of double negative metamaterials structure having ...

Metamaterials, as artificial media, are comprised of sub-wavelength array elements that exhibit exceptional electromagnetic characteristics-negative permittivity, permeability, negative refractive index, perfect prisms, and absorption, to name a few-of particular use in antennas [1], absorber design [2],...
5956Accesses 51Citations 1Altmetric Metrics Abstract All-dielectric nanostructures have recently opened exciting opportunities for functional nanophotonics, owing to their strong optical resonances along with low material loss in the near-infrared range. Pushing these concepts to the visible range is hindere...
