Impact of magnetostriction mechanism on frequency manipulation ultrasonic steering in electromagnetic acoustic transducers
Abstract In this paper, the impact of the magnetostriction mechanism is considered as the focus. An axisymmetric FEM model of the spiral‐coil electromagnetic acoustic transducers (EMAT) is established to conduct the simulation. The simulation results demonstrate that the directivity of ultrasonic wa...
