Tunability of Superconducting Metamaterials
IEEE transactions on applied superconductivity
Metamaterials are artificial structures with unique electromagnetic properties, such as relative dielectric permittivity and magnetic permeability with values less than 1, or even negative. Because these properties are so sensitive to loss, we have developed metamaterials comprised of superconducting waveguides, wires, and split-ring resonators. An important requirement for applications of these metamaterials is the ability to tune the frequency at which the unique electromagnetic responsedoi:10.1109/tasc.2007.898535 fatcat:unjxybsdyrdopgm6kko6nbrv2q
