MICROSOUND COMPONENTS, CIRCUITS, AND APPLICATIONS

Abstract

Acoustic analogs of conventional microwave transmission line (microsound) components on the surface of crystalline substrates should find application in wideband, high-capacity signal and data processors. These microsound transmission lines, hybrids, and couplers interconnect microsound transducers, amplifiers, isolators, and phase shifters to form microsound circuits capable of autocorrelation, Fourier transformation, and matrix permutation functions. Compatible component configurations are proposed and evaluated which perform the basic functions of wave guidance, amplification, isolation, and transduction. The anticipated difficulties with their realization is discussed, and the status of critical problems, including the epitaxial growth of acoustic thin films and sub-micron etching procedures, will be given. Several circuits capable of autocorrelation, cross correlation, Fourier transformation, and matrix permutation are described.
