Abstract :
A novel nonlinear phenomenological two fluid model for High Temperature Superconductor (HTS) is proposed. The model combines the physics associated with the Ginzburg-Landau expressions and the required simplicity obtained from the linear London´s equations. An empirical formula for the nonlinear surface impedance is suggested based on the developed model. Analysis of HTS filter using this novel nonlinear formulation is presented.
