Growth of Tl2Ba2CaCu2O8 superconducting thin films on curved substrates for metamaterials applications

Terahertz superconductor metamaterial

“…Fedotov et al showed the Fano resonances in microwave YBCO MM and observed the interaction between electrical and magnetic dipoles [25]. In 2007, another type of HTS, thallium barium calcium copper oxide (TBCCO) was used by S. Speller and co-workers to fabricate MM structures on curved surfaces [26]. Thus, most of the previous works on superconductor MMs were focused in the microwave regime and since the behavior of HTS is frequency dependent, it becomes highly essential to investigate HTS MMs at higher frequencies of operation.…”

Metamaterials for microwave frequencies

“…The ceramic particles contribute to the effective negative permeability due to Mie resonance, while the conducting wire frame provides the effective negative permittivity [122]. A promising candidate for metamaterial devices is TI-2212 grown on MgO cylinders [123]. This composite creates a coupled resonator structure that can manipulate magnetic fields on a scale shorter than a wavelength [123].…”
