  • 1. Warwick Univ., Coventry (UK). Dept. of Physics

Description

The fabrication of electromagnetic acoustic transducers (EMATs) is described. Neodymium iron boron permanent magnets allow compact devices to be constructed. Pick-up mechanisms in both magnetic and non-magnetic metals are discussed and demonstrated experimentally EMATS are suitable detectors for broadband laser generated ultrasound such systems, being non-contacting, can operate at high temperature
