The detection of porosity changes within a soil matrix caused by internal erosion is beneficial for a better understanding of the mechanisms that induce and maintain the erosion process. In this paper, an electromagnetic approach using Spatial Time D

We propose a method for reconstructing 2D surface cracks in electrically conducting parts from Eddy-current images. The proposed method relies on the use of a direct semi-analytic model suitable for Eddy-current systems featuring a uniform current ex
