Aluminium sheet thickness has been calculated from ultrasonic data obtained using a sendΒ±receive, radially polarised electromagnetic acoustic transducer (EMAT). Sheets in the thickness range between 0.1 and 0.5 mm have been measured using this noncontact approach at a stand-o of up to 1.5 mm. Normal
