摘要： An acoustic wave device employing surfaces skimming bulk waves comprises a piezo electric substrate having a flat surface which carries an input transducer and an output transducer for respectively lanuching and receiving acoustic waves into and from the bulk of the substrate. The substrate may be of quartz, lithium tantalate, or lithium niobate and has the flat surface orientated so that a surface skimming bulk wave is launched without generation of surface acoustic waves.

摘要： The present invention relates to the modification of the temperature-induced drift in propagation time of surface elastic waves. The invention proposes to achieve this modification by selecting a suitable crystal cut of the crystalline substrate, and carrying out a localized ion bombardment of the surface at which the elastic waves propagate.

摘要： A fiber acoustic waveguide comprising a single crystal fiber and a single ystal film deposited on the outer elongated surface of the single crystal fiber, wherein the single crystal film has a higher velocity of propagation than the single crystal fiber. The fiber acoustic waveguide has a delay that is directly proportional to its length, whereupon fixed lengths of the waveguide provided fixed delay.A fiber acoustic waveguide system is provided by connecting one end of the waveguide to driving transducer means for converting an electrical signal to an acoustic signal, and the other end of the waveguide to pickup transducing means for converting the transported acoustic signal from the waveguide back into an electrical signal.
