  • Abstract
    The topological gradient (TG) is derived for Steady state Eddy Current problem using a topological asymptotic expansion for the Maxwell equation of a Time Harmonic problem. TG provides information on where the design is most sensitive to topology changes. An application to eddy current nondestructive testing (NDT) is demonstrated.
