A reconfigurable metasurface sub reflector comprises an array of cell units. Each sub unit is formed of two sub-unit cells formed with at least two conducting layers separated by a dielectric substrate. One conducting layer has, in each of the sub-unit cells, two parallel strips connected by a varactor and the other conducting layer serves as a ground layer. Setting the reverse biasing for each of the varactors controls the azimuth and elevation of reflection from the reconfigurable metasurface sub reflector.

Apparatus and method for detecting a dissolved gaseous impurity in an aqueous environment, comprises a tube for isolating liquid surface, or a sampler for obtaining a liquid sample from the aqueous environment, a vacuum pump located to exert a vacuum, leaving the surface to evaporate into the vacuum; and a holding compartment for holding evaporated gas which may then be analyzed using electrochemical or spectroscopic methods. The apparatus is useful for detecting levels of ammonia in fish ponds or indeed any impurity that may be dissolved in the water.

An upconversion system, including: a glow discharge device (GDD) configured to detect signal source radiation, wherein the signal source radiation is at least one of millimeter wave (MMW) radiation and Terahertz (THz) radiation; and a photodetector configured to measure intensity changes in visible light emitted by said GDD as a result of absorption of the signal source radiation. The upconversion system optionally includes a processor operatively coupled to the photodetector. The processor is configured to analyze imagery captured by the photodetector, and to compute at least one parameter of the signal source radiation based on the imagery.
