Abstract

In conventional methods, a 3-D scalar potential problem must be solved in order to obtain a current source producing magnetic fields. In the proposed method, electric power is supplied to a region under consideration by the Poynting vector of a transverse electromagnetic (TEM) wave through a semi-infinite twin-lead-type feeder. Therefore, it is sufficient to solve the 2-D Laplace equation of the TEM wave before the calculation of the 3-D eddy current problem. Numerical analyses of conducting electrodes are shown. Reasonable results with phase lag and skin effect are obtained
