  • Planar gradient index optical metamaterials
    Patent number: 8300294
    Abstract: An apparatus comprises a metamaterial including a first conducting layer, a second conducting layer, and a dielectric layer located between the first conducting layer and the second conducting layer. Each conducting layer has holes formed therethrough, for example as an array of holes formed through the metamaterial. The holes are configured so that the metamaterial has a gradient refractive index at an operational wavelength. The operational wavelength may be an IR or visible wavelength. The apparatus may be an optical element, and for example may have the functionality of a lens or prism through the gradient refractive index. Interfaces may be parallel planar interfaces.
