Abstract
An integrated sub-millimeter and infrared reflectarray includes a reflective surface, a dielectric layer disposed on the reflective surface, and a subwavelength element array and a subwavelength element array electromagnetically coupled to the reflective surface. The subwavelength element array includes (i) electrically conductive subwavelength elements on the dielectric layer, (ii) wherein the dielectric layer comprises a plurality of dielectric subwavelength elements, or (iii) the dielectric layer includes a plurality of embedded dielectric subwavelength elements. The array includes at least one of a plurality of substantially different inter-element spacings and a plurality of substantially different dimensions for the elements.
