Abstract: In this paper, the eddy current nondestructive evaluation method is used to determine the electrical conductivity, the thickness and the size of a deposit located on the reverse side of a tested specimen. The eddy current probe consists in a coil. The impedance of the coil is calculated by a boundary integral method. The inverse problem is solved by combining a neural network and an iterative resolution.
