METAMATERIAL HAVING A HIGH REFRACTIVE INDEX

摘要

The present invention provides a metamaterial having a high refractive index that cannot be found in natural materials. The high-refractive-index metamaterial includes a dielectric substrate and a conductive layer formed on the dielectric substrate. The conductive layer includes a plurality of unit grids defining a specified gap therebetween. The metamaterial has a refractive index equal to or larger than the refractive index of the substrate in a predetermined frequency range.
