Josephson coupled superconducting multi-layers as tunable metamaterials

This project is devoted to a study of high-frequency electromagnetic field propagation in layered superconductors, which can be considered as superconducting metamaterials due to anisotropic dielectric properties. In addition to their low loss, compact strcture and nonlinear properties, these structures present unprecedented level of controllability for the propagation of electromagnetic waves, which are not available in standard materials. Quantum metamaterials are also considered in an example of a chain of identical superconducting charge qubits inside a superconducting resonator. In such a medium the coherent quantum dynamics of qubits determine the properties of the system, leading to interesting physical processes.
