摘要:
A staggered magnet array (SMA) based electromagnetic acoustic transducer (EMAT) system and method for controlling the direction of the ultrasonic waves in the electromagnetic acoustic transducer (EMAT) using staggered magnet array (SMA) configurations, is disclosed herein. The EMAT device proposed herein comprises at least one conductive racetrack coil and at least two magnet arrays wherein the magnet array comprises of permanent magnets, where each magnet is oriented according to a specific configuration to produce ultrasonic waves in order to form an ultrasonic beam by shifting the position of the magnet arrays up or down creating a SMA configuration.
