Abstract: Skin and proximity effects are calculated in both active and passive conductors via a subproblem finite element method based on a perturbation technique. A reference limit problem is first solved by considering either perfect conductors or magnetic materials via appropriate boundary conditions. Its solution gives then the source for the eddy current perturbation subproblems in each conductor with its actual conductivity or permeability and its own mesh. The proposed method accurately determines the current density distributions and ensuing losses in conductors of any shape in both frequency and time domains, which overcomes the limitations of the impedance boundary condition technique.
