Abstract :
Transient propagation of Gaussian pulses on superconductive conductor-backed coplanar waveguides are investigated using the Finite Difference Time Domaim Method (FDTD). The two-fluid model is used to describe the superconductivity. The frequency-dependent negative imaginary part of the conductivity is modeled with the FDTD by storing the electric field history. A variable mesh with second order accuracy is used to resolve the thin superconductor film and buffer layer.
