Metamaterial devices for optical absorption, dispersion and directional sensing

An optoelectronic metamaterial directional sensor for selectively sensing electromagnetic radiation entering the sensor at a target angle of incidence, the directional sensor comprising:

• an optically transparent prism, the optically transparent prism comprising a wide range optically transparent material that transmits electromagnetic radiation in at least a visible region and an infrared region of an electromagnetic spectrum, the prism further comprising a lens surface exposed to an electromagnetic radiation source, a sensor surface adjacent to at least one sensing device and an absorbent surface adjacent to an optically absorbent material,
• the sensor surface divided into a plurality of segments, wherein at least one segment of the plurality of segments corresponds to a target angle of incidence of an electromagnetic wave entering the prism through the lens surface,
• wherein the at least one segment of the sensor surface is abutting the at least one sensing device and the remaining segments of the plurality of segments of the sensor surface are abutting the said optically absorbent material.
