The Coupling Surface Method for the Solution of Magnetoquasi-Static Problems

In this paper, we present a novel methodology for decoupling the solution of the magnetoquasi-static equations in subdomains through a coupling surface and related equivalent currents. In particular, the solution outside the coupling surface is condensed with a suitable boundary condition. Different formulations can be used in each subdomain, hence allowing the most convenient approach to be used in each case. Some examples of the application are presented, showing the effectiveness of the method.
