review text: The technique described here relies on the fact that the wave equation can be decomposed into into incoming and outgoing wave modes at the boundary. The result is a modified wave equation for the boundaries which automatically includes the boundary condition. The boundary treatment is applied to a realistic problem of ultrasonic wave propagation through a vertical interface separating an anelastic solid from an elastic solid at the surface. The results show that the method correctly describes the anelastic properties of the Rayleigh wave in the presence of a strong contrast in the material properties.
