Sg. Suchkov, EMISSION OF A SURFACE-ACOUSTIC-WAVE BY AN INTERNAL ACOUSTIC-WAVE PROPAGATING NEAR-THE-SURFACE, Technical physics letters, 24(9), 1998, pp. 731-732
It was observed that the propagation of an internal acoustic wave near
a surface is accompanied by the excitation of a surface acoustic wave
directed at an angle to the internal wave. (C) 1998 American Institut
