Dynamic Plasma/Metal/Dielectric Crystals

Caption

Dynamic plasma/metal/dielectric crystals are able to filter electromagnetic signals in the 100-300 GHz range, transmitting desired frequencies at any given moment of time. White light impinging on the crystals symbolizes broadband mm-wave signals that are filtered by the crystals, allowing only narrowband radiation (symbolized by red, green, or blue beams) to exit the crystal.
