This paper describes a non-contact ElectroMagnetic Acoustic Transducer (EMAT) that can be used to generate both Lamb and Rayleigh waves on metal samples. The generated waves are wideband and low frequency with a dominant frequency content centred on approximately 200kHz extending to around 500kHz. Detection of the waves is achieved using a linear coil detection EMAT. The transducers (generator & detector) have been used on both aluminium and steel, but operate more efficiently on aluminium due… CONTINUE READING
