Abstract :
We present a method to calculate the current density distribution, the magnetic field distribution and the inductance matrix of three dimensional superconducting structures by minimizing the free energy. In the case of high-Tc superconductors, the kinetic inductance becomes substantial and an accurate calculation of inductances is required. The London penetration depth λ and the kinetic inductance are included. The results of a program which realizes this method agree well with measurements of high-Tc dc-SQUIDs (superconducting quantum interference devices)
