Surface Acoustic Waves
Surface acoustic waves have been a subject of scientific investigation for more than hundred years. Lord Rayleigh [2.1] showed in 1887 that a semi-infinite, isotropic, elastic medium, bounded by a single stress-free planar surface, can support propagating modes that are wavelike in directions parallel to the surface. These excitations are identified as surface waves because they are characterized by acoustic fields that decay exponentially with distance into the medium from the surface, and by a frequency that is linearly proportional to a two-dimensional wave vector, which lies in the plane of the surface. The displacements of the medium lie in the sagittal plane, which is defined by the normal to the surface and the direction of propagation of the wave. In honor of their discoverer, they are known as Rayleigh waves.
