Oblique Point-Focusing Shear-Horizontal Guided-Wave Electromagnetic Acoustic Transducer With Variable PPM Spacing
We realized a phase-coherent oblique point-focusing shear-horizontal (SH) guided-wave electro- magnetic acoustic transducer (EMAT) composed of variable-spacing periodic permanent magnets (PPMs) and racetrack coils. For traditional focusing transducers, the necessary focal position adjustment in defe...
