Tunable and high quality factor Fano and toroidal dipole resonances in terahertz superconducting metamaterials

We experimentally studied a series of terahertz (THz) metamaterials with asymmetric resonator structures made from superconducting niobium nitride or gold films. Fano and toroidal dipole resonances are excited in superconducting metamaterials and their quality factors are higher in comparison with t...
