Superconducting Quantum Interference Filters — •Nils Schopohl — Institut für Theoretische Physik der Universität Tübingen

Basic principles of Josephson junction based interferometer arrays are reviewed. Key features of parallel and also serial Superconducting Quantum Interference Filters (SQIFs) are explained in detail. It is shown that SQIF interferometers can be engineered to have a specific voltage output pattern vs. magnetic field that is well suited for applications in magnetometry and also microwave sensorics.
