Abstract
Metamaterials are artificial engineered media that enable tailored interactions with electromagnetic waves. The design flexibility of superconducting thin-film resonators and Josephson circuits allows for utilizing small structures down to the nanoscale while maintaining low loss properties, very strong and well-controlled nonlinearity, and frequency tunability in the microwave and mm-wave frequency ranges. An interesting spin-off here is going to be quantum metamaterials comprised of arrays of superconducting qubits.

Summary

I will review progress in the development of superconducting metamaterials. There are several distinct advantages and unique properties brought to the metamaterials field by superconductivity. These include the low-loss nature of the meta-atoms, their compact structure, their extraordinary degree of nonlinearity and tunability, magnetic flux
quantization and the Josephson effect, quantum effects in which photons interact with quantized energy levels in the meta-atom, as well as strong diamagnetism.
