The paper describes a 3D semi-analytical harmonic modeling technique, which is capable to model eddy current distributions in conducting structures and the associated fields. The induced current density and magnetic fields in the spectral domain are described, where a spatially varying conductivity of a conducting region is incorporated in the solutions of magnetic-field quantities. An experimental setup is used to measure the field distribution above differently shaped conducting plates, placed on top of a coil, in which eddy currents are induced. The measurement results are compared to simulation results and the perturbations are analyzed.
