摘要：
The study of using Electromagnetic Acoustic Transducer (EMAT) to generate and detect the low frequency Lamb wave A0 mode in the thin steel plate is described. On the base of analysis of dispersion curves, a Lorentz force type EMAT is designed to generate and detect the single Lamb wave A0 mode in the low frequency range of 0-300kHz in 1-2mm thin steel plate. The preliminary experiments are presented on the generation of the low frequency A0 mode, and the detection measurement using the low frequency A0 mode in the steel plate with a defect.
