Abstract
The mathematical demonstration given by Lord Rayleigh about one century ago [9.1] that the long-wave (L) component of earthquakes is due to sagittal surface elastic waves is commonly considered the starting point of surface physics. The theory of Rayleigh waves and other types of surface waves in semiinfinite elastic continua very soon left the realm of geophysics and attracted the interest of solid state physicists and materials scientists due to the potential of surface acoustic waves (SAW) for applications in delay lines, optoacoustic systems and signal processing devices [9.2]
