Abstract This paper is concerned with transmit-receive mechanism of the electromagnetic ultrasonic tran sducer (EMAT) for the guided wave. First, the three-dimensional guided wave propagation simulator is de veloped. This simulator calculates the particle velocity from the force which are excited by EMATs with FDTD method. Second, configuration of EMATs is designed based on our study of the excitation mechanism of an EMAT, in order to transmit and receive the longitudinal mode (L-mode) or the torsional mod...
