Realization and Modeling of Metamaterials Made of rf Superconducting Quantum-Interference Devices
A radio receiver that can tune to and digitize millions of frequencies per second, even if the signals are very weak, requires isolating the desired signal from stronger, unwanted noise. Scientists demonstrate a new kind of metamaterial, built with individual radio-frequency superconducting quantum-interference devices (rf SQUIDs), that allows such fast …
