Surface Acoustic Wave Transducer Study.
Abstract
A theoretical and experimental study of surface acoustic wave transducers is carried out to improve the modeling technique and the implementation configuration. The capacity weighted transducer with the response controlled by integrated circuit capacitors has been developed. The response is improved because the SAW beam has a uniform width and the transducer taps may be adjusted over a wide range. The excitation theory of transducers has been reformulated to account for nearest neighbor interactions over a wide range of harmonics. This modeling approach significantly expands the versatility and accuracy of the model. An experimental procedure for measuring the transducer excitation function is described. (Author)
