1. A method of forming a Luneburg lens, comprising:
providing a spherical core formed of a material with a substantially uniform dielectric constant from a center of the spherical core to an outer surface of the spherical core;
forming a plurality of holes substantially uniform in size and symmetrically located about the center of the spherical core; and
forming an at least one outer layer that is substantially spherical by winding a filament formed of a low-loss material around the spherical core.
