We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module (general form) and solves Maxwell equations using a highly non-linear resistivity to describe the superconductor electrical characteristics.

The time-dependent magnetic flux and current distribution of multifilamentary thin films are studied for different geometries by changing the distance between the filaments. Our model describes accurately the current and flux dynamics as we would expect from the characterization of real multifilamentary systems.
