Eddy current techniques for nondestructive testing and evaluation (NDT/NDE) of conducting materials is one of most application-oriented field of research within electromagnetics. In this paper, quantitative NDE of corrosion in metallic plates is considered. The inspection method exploits impedance measurements to determine the material loss profile caused by corrosion. Considering the corrosion shape as a function of impedance measurements, it has to be minimized in order to obtain the corrosion profile. In particular, swarm intelligence, characterized by evolutionary computation, has been exploited for the purpose. The proposed approach has been compared with results known in scientific literature both for performances and time consuming, with encouraging results
