https://doi.org/10.1007/978-3-642-47714-0Many EMATs have been developed for bulk waves, surface waves, guided waves, wave focusing, and applications to materials in move and at elevated temperatures. An antenna transmission technique for piezoelectric materials is also proposed. This chapter presents various EMAT structures and their operating principles.

Organisation der geistigen ArbeitThis chapter reviews the EMAR application to determine the average grain size of carbon steels (Ogi et al. .) on the basis of the fourth-power frequency dependence of attenuation. The final results are favorably compared with the average of three-dimensional distribution from metallographic observations for various grades.

In-Situ Monitoring of Dislocation MobilityThe noncontacting measurement with EMAR allows not only accurate evaluation of absorption loss inside materials but also such measurements at low and high temperatures and during deformation. This chapter shows many applications of EMAR for studying dislocation mobility and interactions between dislocations and point defects.
