Propagation of Pure Shear Surface Waves in Magnetostrictive Polycrystalline Ferrites

Vladimir Ermolov and M. Luukkala

ABSTRACT The launching and propagation of pure shear surface waves (SSW) in magnetostrictive polycrystalline ferrite were studied. The results show that SSW have lower sensitivity to surface quality than Rayleigh waves, but the launching effectiveness by meander-type transducer is lower than for Rayleigh waves. The variation in phase velocity of SSW on a magnetic field was 4.5%, which can be of interest in applications.
