Abstract
Josephson junctions can be arranged in a metamaterial
configuration, forming an artificial one-dimensional
medium for microwave propagation, which enables fast
tuning of the speed of light by an external magnetic
field. This metamaterial has been used for parametric
amplification and as a demonstrator of the dynamical
Casimir effect. An important property of
metamaterial-based devices is damping, which is
fundamentally limited by mechanisms related to the
Josephson junctions themselves. In this paper we derive
theoretical models for two such mechanisms, the
quasiparticle tunneling and the dielectric loss within
the material of the tunnel barrier. We discuss whether
the junction-based effects are likely to be the limiting
factors in the experimentally observed quality factors of
metamaterial-based resonators.
