The theory of SH-wave generation by electromagnetic-acoustic transducers (EMATs) and the representation of the waveform in propagating plate modes was developed in [1]. Since then several theoretical and experimental studies have been reported that deal with SH-wave scattering by normal flaws (cracks) and its use for sizing these cracks [2–10].
