摘要：Chalcogenide glass is deposited on a nonpiezoelectric substrate by vapor deposition techniques to form thereon a wedge of chalcogenide glass, the sloping surface of the wedge being disposed at a preselected angle with the surface of the substrate. The interface between the substrate and the chalcogenide glass thus deposited is substantially free from defects that generate acoustical interference at high frequencies. A piezoelectric transducer is then evaporated onto the surface of the wedge. A microwave frequency signal applied to the transducer generates bulk waves in the chalcogenide glass wedge. These bulk waves propagate through the wedge and impinge the substrate at regularly spaced intervals, thereby generating Rayleigh (surface) waves in the substrate.
