Finite difference modelling of non-linear behavior in high temperature superconducting transmission lines

A two dimensional finite difference analysis of high temperature superconducting (HTS) strip transmission lines is presented. In particular, the nonlinear response of the HTS striplines to high RF currents is modelled. The anisotropic Ginzburg-Landau equations are used in conjunction with the time-harmonic Helmholtz wave equation to form a general purpose analysis tool for the study of various geometries and HTS materials
