Abstract :
A surface wave transducer using a thin ferroelectric film deposited atop silicon and periodically poled has been theoretically analysed. Fundamental guiding properties of such devices are extracted from numerical computations. A low frequency validation of the proposed principle is reported using a periodically poled PZT plate glued on a silicon wafer.
