Abstract
An acoustic wave signal processing device which in a preferred embodiment utilizes at least one holographic grating formed within a portion of the interior of a substrate which is capable of supporting the propagation of bulk acoustic wave signals therein. The grating provides spatially varying acoustic impedances within the substrate and interacts with bulk acoustic wave signals propagated therethrough so as to produce output acoustic wave signals. The grating and transducers for producing and receiving the input and output bulk acoustic wave signals, respectively, can be arranged to provide a variety of signal processing operations which may be desired, such as providing resonating operations and filter operations, for example.
