摘要：
Surface acoustic wave (SAW) propagations along DELTA V/V waveguides at an angle 30 degree to Z crystal axis on Y-cut LiNbO//3 were observed by the FTH (Frequency Translated Holography) method, and the results showed the efficient guiding effect of the waveguides. On the multimoded waveguides, complicated SAW propagation patterns were observed, and were expected to be related to the higher-order-mode excitations. The mode excitations at the entrance of the waveguide were studied theoretically by the method of modal analysis, and the theoretical propagation patterns on the waveguides were found to be fairly consistent with the observed patterns.
