Abstract
This work is dedicated to the theoretical modelling of the eddy curren t transducer with orthogonal coils destined to control flat metallic s urfaces. The exact solutions of the Maxwell equations for the assembly transducer-conductive half-space are obtained by modelling the curren t source by a Dirac distribution and using the dyadic Green functions of the problem. Theoretical solutions are presented describing the tra nsducer operation in the presence of a discontinuity in the conductive medium. (C) 1997 Elsevier Science S.A.
