Abstract

Superconductors may be considered as plasmonic media, exhibiting a resistance dominated by the kinetic motion of electrons and a negative dielectric constant. In metamaterials Joules losses are significant and substantially reduce achievable Q-factors. The use of superconductors in metamaterials permits the control and reduction of Joule losses, opening the opportunity for achieving low-loss, high Q-factor metamaterials.
