摘要： A multidomain plate acoustic wave device is provided having one or more single piezoelectric crystalline plates with differently polarized ferroelectric domains, where the domains have diverse directions of their axes of polarization. The device may consist of a multidomain plate acoustic wave transducer, a multidomain plate acoustic wave delay line, a multidomain plate acoustic wave rf filter, and any combination thereof. The differently polarized ferroelectric domains may comprise a collection of inversely or differently poled ferroelectric domains within a single piezoelectric medium. The medium may be any crystalline or ceramic plate with non-zero piezoelectric properties, in which the domains are created and embedded. In varying embodiments, the device includes electrodes oriented to generate an external rf field in various, respective directions, including in a direction normal to a basal plane of the device, or in a direction parallel to a length or a width of the device.
