Field theory investigation of high-T/sub c/ superconducting coplanar waveguide transmission lines and resonators

An investigation is conducted of a coplanar waveguide structure using a partial wave synthesis taking into account the complex conductivity of the high T/sub c/ superconductor material according to the two-fluid model and the London theory. Micrometer transmission line dimensions are considered in the frequency range up to 100 GHz. The results obtained for superconductors are also compared with the results obtained for superconductors with real conductivity and the same geometry. The behavior of measured and published coplanar waveguide half wavelength resonators made of high-T/sub c/ superconducting thin films is also examined.<
