An array of two or more tunable electro-optical reflecting elements where the phase response of one or more elements may be adjusted by a variety of approaches including, but not limited to: a liquid crystal superstrate, schottky contact(s), ultra-violet radiation pulses, and illumination of photoconductive substrates. Methods and apparatus for direct and/or adaptive control of phase response via the above approaches are also discussed.

Dynamic reflectarray technology for electro-optical sensors

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.
