摘要：
We propose a novel piezoelectric inter-digital transducer (PIT) based on alternately poled domains of a ferroelectric thin film deposited on top of a single crystal substrate. This transducer offers an alternative to the inter-digital transducer (IDT) for the excitation of very high frequency surface acoustic waves (SAW). An experimental validation of the approach is reported in a 1-4 GHz frequency range, confirming theoretical predictions.
