Magnetostrictive phased array transducer for transducing shear horizontal bulkwaves
Abstract:
A magnetostrictive phased array transducer for transducing shear horizontal bulkwaves including a plurality of magnetostrictive members each having a bottom surface of a plate-shaped structure made of a ferromagnetic material, which is mounted to be adhered closely to the surface of a mounting place; an insulator disposed on a side surface of each magnetostrictive member; a meander coil having a plurality of coil lines extended in the direction parallel with the bottom surface on each insulator, wherein adjacent coil lines are connected so that current flows in the opposite directions to each other, thereby generating a dynamic magnetic field with respect to each magneto strictive member; and a magnet mounted to generate a static magnetic field perpendicular to the dynamic magnetic field. When the current is supplied to the meander coil, a plurality of magnetostrictive members generate a plurality of shear horizontal bulkwaves while being deformed by the magnetostriction effect.
