ABSTRACT:
A structure is described that includes a plurality of columnar pieces of metamaterial, and a plurality of columnar pieces of non-metamaterial. The columnar pieces are arranged in an alternating pattern adjacent one another, and the metamaterial and the non-metamaterial are chosen such that indices of refraction for each are equal in magnitude, but opposite in sign, at a chosen wavelength, such that incident radiation is returned directly towards its source.
