Abstract

The modified hybrid integrodifferential finite element (IDFE)-Green´s function method is extended to the solution of 2-D unbounded eddy current problems under transverse magnetic (TM) field excitation. To illustrate this formulation, the magnetic vector potentials (MVPs) of a solid and a hollow conducting cylinder under TM field excitations are computed. Current distributions and power losses are obtained. The formulation is validated by comparing calculated results with analytic solutions
