When a circular magnetostrictive patch bonded to a plate is subjected to static biasing and dynamic actuating magnetic fields, the patch deformation generates guided waves in the plate. To fully understand the characteristics of the circular patch-based transducer, the radiation pattern of the Lamb waves for arbitrary relative orientations of the two fields was experimentally investigated. The largest Lamb wave in an aluminum plate was generated when the two field directions make some oblique angle around 70°, not when they are parallel. The experimental findings were explained by a theoretical analysis.
