Abstract

We present a method to calculate the inductance matrix of three dimensional superconducting structures by minimizing the free energy. In the case of high-T/sub c/ superconductors, the kinetic inductance becomes substantial and an accurate calculation of inductances is required. The London penetration depth /spl lambda/ and the kinetic inductance are accurately included by this method. The results of this program agree well with measurements of high-T/sub c/ DC-SQUIDs (superconducting quantum interference devices).<>
