Abstract
Through stationary-phase asymptotic analysis of the elastic Green's function for a semi-infinite anisotropic elastic solid, we calculate the focusing of surface phonons. We present results for surface-phonon focusing on the (100), (110), and (111) surfaces of NaCl, Ge, and Cu. In addition we present results showing that pseudosurface waves will also be focused.Keywords
