Abstract


Metamaterials provide an new set of tools for the development of diffractive optics. Diffractive optics represent an excellent match for metamaterials, since very few metamaterial layers are needed to accomplish beam-forming or imaging functions. Given the inherent losses associated with metamaterials—especially those formed using metal inclusions—diffractive optics provide a viable compromise, and may ultimately provide an important connection to closely related transformation optical media. Here we describe the opportunities that metamaterials enable, providing recent examples of metamaterial based diffractive optics.
