Electromagnetic Acoustic Transducers for In and Out of plane Ultrasonic Wave Detection
A model has been developed for the detection of ultrasonic waves using electromagnetic acoustic transducers (EMATs). EMATs are particle velocity sensors, which can be designed to have sensitivity to in-plane and/or out-of-plane ultrasonic displacements, by suitably arranging the magnetic field in the receiving EMATs relative to the orientation of the coil. Good agreement between the results from the modeling undertaken and experimental measurements has been demonstrated.
