ABSTRACT
Since Lord Rayleigh predicted their existence (Rayleigh 1885), surface waves have attracted the interest of an increasing number of researchers embracing disciplines as diverse as solid-state physics, microwave engineering, geotechnical engineering, nondestructive testing, seismology, geophysics, material science, ultrasonic acoustics, and others. Despite their marked differences, these disciplines share the goal of exploiting surface waves propagating along the boundary of a domain to obtain information about the interior of that domain, usually expressed in terms of one or more scalar fields.
