Single SH guided wave mode generation method for PPM EMATs Project supported by the National Natural Science Foundation of China (Grant No. 51977044)

Using periodic permanent magnet (PPM) electromagnetic acoustic transducers (EMATs), different shear horizontal (SH) guided wave modes can form simultaneously in some situations, which can interfere with the inspection. The main cause of this phenomenon (typically named multiple modes) is related to...
