It is shown that a shear vertical (SV) wave propagating along a surface of a test object can be transmitted and received by angle probes whose angle of refraction is close to a critical angle. In order to investigate this phenomenon; simulation is carried out using the finite difference time domain method. According to the acoustic fields obtained by the simulation; the beam width of a SV wave increases with propagation; and energy associated with the SV wave exists at the surface. Therefore; the transmitted pulse can be received. The phenomenon of SV wave propagation is referred to as SVC (SV wave for a critical angle). This simulation result is verified by an experiment; which showed that the transmitted pulse is applicable to the measurement of SV wave velocity. © 2007 The Japan Society of Applied Physics;
