Scattering of an obliquely incident Rayleigh wave in an elastic quarterspace
We study the three-dimensional problem of scattering of waves in a homogeneous, isotopic, linearly elastic quarter space. We obtain an equation for the Fourier transform of the normal displacements on the free surfaces. For oblique incidence of a Rayleigh surface wave, we numerically solve this equation. Reflection and transmission coefficients are plotted versus angle of incidence. For angles of incidence smaller than a critical angle, we observed that no energy is radiated into the solid by body waves. The farfield scattering patterns are also plotted.
