Notizen:
A transient line source, either mechanical or electrical, on the surface of a piezoelectric medium will excite electromagnetic acoustic (EMAC) head waves between quasi-electromagnetic surface disturbances and quasi-acoustic waves. EMAC head waves are acoustic in nature, with plane fronts practically parallel to the surface and traveling at acoustic speeds. One such plane wave front is observed experimentally in a thick lead titanate-zirconate plate in accordance with theory.
