8. Advances in Electromagnetic Transducers
I'm going to talk about the use of electromagnetic acoustic wave transducers, or EMATS as I call them, as they are being used for bulk wave generation. They have been applied specifically to the problem of measuring the intensity distribution of acoustic waves that are scattered by defects of known geometries. Related studies have been done elsewhere for some time and have formed an integral part of this general program.
