A fast algorithm for solving 3-D eddy current problems with integral formulations

The aim of this paper is to present an efficient technique for the fast solution of three-dimensional eddy currents problems. The method combines Fast Fourier Transform (FFT) on a regular grid for the calculation of long-range interaction, and the standard method for evaluating the short range interaction.
