IR and metasurface based mm-wave camera

We have developed a technique to measure low-power electromagnetic fields from mm-wave devices non-intrusively by combining metasurface, designed absorb power and focus the radiated in thermally isolated region, with an infrared (IR) camera. The metasurface consists of elements low mass highly emissive material for maximal IR conversion incident wave. camera captures converted energy indirectly images field on metasurface. setup combines multi-scale, multi-physical processes conduct measurements real time. In this work, is presented discussed. Measurements are carried out demonstrate image radiating device. results compare well simulations, can density levels consumer provide general visualization live setting.
