Abstract
A gradient index lens for electromagnetic radiation includes a dielectric substrate, a plurality of conducting patches supported by the dielectric substrate, the conducting patches preferably being generally square shaped and having an edge length, the edge length of the conducting patches varying with position on the dielectric substrate so as to provide a gradient index for the electromagnetic radiation. Examples include gradient index lenses for millimeter wave radiation, and use with antenna systems.
