Fast signal predictions of noised signals in eddy current testing

This paper describes a new method for the simulation of signals noised by the presence of other materials outside of test materials in eddy current testing. The method developed here, which can treat ferromagnetic materials, is an extension of a pre-computed database approach based on the magnetic vector potential method. It results in much fewer degrees of freedom than those of typical finite element approaches, and the method provides a very fast forward simulator even in the case with ferromagnetic materials.
