Abstract

This paper describes numerical analysis of current limiting characteristics of YBCO thin film with inhomogeneous superconducting properties. The analysis tool uses a finite element method (FEM) based on current vector potentials. First, the validity of the analysis tool was verified by comparing with experimental results using small samples. Then we analyzed large-size meander-shaped thin films and discussed the influence of inhomogeneous superconducting properties of YBCO thin film on current limiting characteristics.
