Description
Superconducting QUantum Interference Devices (SQUID)s are superconducting loops broken by one or more Josephson junctions and act as RLC circuits with a resonant frequency that can be tuned by an applied magnetic field. A microwave metamaterial can be created by positioning many of these SQUIDs in an array such that such that their spacing is much less than that of the microwave wavelength. In this work, the extent the resonant frequency of an accelerator cavity can be shifted for a given coupling with a SQUID metamaterial is obtained with two models. From this, it is considered if the cavity resonance shift is sufficient for weak enough couplings that such a cavity tuning scheme could be relevant for accelerator applications.
