“…The result of this technology, a &dquo;tagged composite&dquo; that has the ability to respond to magnetic excitation, offers good opportunities for developing new NDE methods and tech-niques. Several theoretical studies (Sun, Liang, Rogers, and Vick, 1993;Rogers et al, 1995;Quattrone, 1995a and1995b) have been performed to assess this technology and to find the most promising methods for in-service and in-field implementation.…”
