Preferable Configurations for SAW-Like Devices Using LN/LT Thin Plate

Presently, various SAW-like device structures employing LN/LT thin plate are paid much attention for realization of unique features which are not achievable in conventional SAW technologies such as high quality factor, large electromechnical coupling factor, large or small acoustic wave velocity, etc. Nevertheless, guidelines for their structural design seems unclear. This talk discusses basic properties of acoustic wave propagation and excitation in thin plates and the discussions are extended to practical multi-layered structures.
