title = "3-D Simulation for the acoustic field directivity of SH-Wave EMATs",
abstract = "The advantages of SH guided waves are that their dispersion characteristics are simple, and the distortion is low when they pass through austenitic welds, thus their application prospect in the non-destructive testing is great. The acoustic field directivity of SH-wave electromagnetic acoustic transducers (EMATs) affects the detection performance. However, the acoustic field distribution of SH-wave EMATs cannot be obtained by a 2-D simulation model. 3-D finite element models of SH guided waves generated by periodic permanent magnet (PPM) EMATs are presented based on COMSOL. The simulation results show that the acoustic field direction angle of SH guided waves is 16.7°. The accuracy of the simulation model is verified by the experimental results.",
