Three-dimensional wave propagation and probe modeling in a homogeneous, linear elastic, anisotropic half-space is discussed. The probe is modeled by modifying the traction vector at the interface between an isotropic half-space and an anisotropic half-space. The traction vector is obtained by considering a plane wave in the isotropic solid incident upon the interface. The probe can be of any type, angle, frequency, and size. The probe is attached to an anisotropic half-space and the wave propagation problem is solved by means of Fourier transform techniques. Numerical examples illustrate some of the properties of the probe model and wave propagation in anisotropic solids.
