ELASTIC WAVE DEVICE WITH SUB-WAVELENGTH THICK PIEZOELECTRIC LAYER AND HIGH VELOCITY LAYER

Abstract:

Aspects of this disclosure relate to an elastic wave device. The elastic wave device includes a sub-wavelength thick piezoelectric layer, an interdigital transducer electrode on the piezoelectric layer, and a high velocity layer configured to inhibit an elastic wave from leaking from the piezoelectric layer at anti-resonance.
