Abstract
A method is presented which can be used to model elastic wave phenomena near a plane interface. The displacement potentials of the reflected or refracted fields are calculated using FFT-based plane wave decomposition and plane wave reflection and refraction. Wavefields are extrapolated from one plane to another by means of a spatial convolution using the Rayleigh 2 operator. Thus, in principle, any incident wavefield can be modeled. Examples are presented for the reflected field of an impulsive monopole line source, located in a fluid over a solid. Except for the Stoneley wave, all surface waves (headwaves, leaky Rayleigh waves) are included.
