Abstract

In this paper we will focus on the modeling of electromagnetic (EM) systems, in the aim of using it in an inversion scheme. The purpose will consists in imaging cracks with eddy current sensors, through an estimation of the conductivity of the piece of metal under test. There are plenty of industrial applications in Non Destructive Evaluations for monitoring of cracks in structures used in Aeronautics, Metallurgy, ships building and so on. For modeling, a relatively new developed technique, called ‘Distributed Points Source Method’ (DPSM) has been used.

Keywords: eddy currents dpsm modeling multi-frequency imaging
