抄録	Based on the finite-difference time-domain (FDTD) method, we study theoretically the wave-front images of acoustic waves propagating on the (100) and (001) surface of a highly anisotropic tetragonal TeO2 crystal for which imaging experiments have recently been conducted. The theoretical images well reproduce characteristic features observed experimentally. The group-velocity calculations of both surface and pseudosurface acoustic waves account for the shapes and locations of the major wave fronts obtained with the FDTD method. Additional weak wave-front structures that disappear rather quickly in time are attributed to bulk acoustic waves.
