Multi-Angle Beam Generation and Steering via Meander-Line-Coil EMATs
… to steer the angle of its oblique ultrasonic waves. This culminates in the innovative generation of multi-angle bulk waves simultaneously from a single EMAT. The practical applications of a multi-angle EMAT include the ability to perform sectoral scans, currently only possible by Phased Array …

Low Temperature Electron Irradiation Induced Defects in Gallium-Arsenide: Bulk and Surface Acoustic Wave Studies
… observed in n-type and semi-insulating GaAs with bulk and surface acoustic waves (SAW) respectively. Bulk waves at eight frequencies between 9 and 130 MHz and SAW at 73 and 145 MHz were used. The reorientation kinetics of both peaks follow the Arrhenius law.
