Patent ID: 7623071

Claim:
An integrated sub-millimeter and infrared reflectarray, comprising: a reflective surface; a dielectric layer disposed on said reflective surface, and a subwavelength element array electromagnetically coupled to said reflective surface, said subwavelength element array comprising at least one of: (i) a plurality of electrically conductive subwavelength elements on said dielectric layer, (ii) said dielectric layer comprising a plurality of dielectric subwavelength elements, and (iii) said dielectric layer comprising a plurality of embedded dielectric subwavelength elements, wherein said subwavelength element array in (i), (ii) and (iii) includes at least one of a plurality of substantially different microscale inter-element spacings and a plurality of substantially different microscale dimensions for said plurality of elements, wherein an operating frequency band provided by said reflectarray is in a range between 1 THz and 500 THz.
