TLDR
In this paper, the processes of transmission and detection by EMATs were analyzed numerically using numerical results of electromagnetic fields induced by the vibration of a vibrational sample. But the results were not validated by experimental results.Abstract:
In this research, the processes of transmission and detection by electromagnetic acoustic transducers (EMATs) were analyzed numerically Computed elastodynamic fields visualize how ultrasonic waves propagate in the specimen, reflecting with mode conversion on the boundary surface Effects of the propagated waves on output signals of a receiver EMAT were discussed by using numerical results of electromagnetic fields induced by the vibration of the specimen Predicted receiver signals agree well with experimental results, which validates our numerical approachread more

Effects of a Flaw on Acoustic Wave Propagation by an EMAT System
T. Sugiura,S. Maruyama +1 more
TL;DR: In this paper, the application of electromagnetic acoustic transducers (EMATs) to nondestructive testing has a potential advantage over conventional ultrasonic testing, because EMATs require no contact between a transducer and a test specimen.
