Abstract

This thesis presents an introduction into surface acoustics wave (SAW) unidirectional transducer (UDT) technologies and identifies advantages and disadvantages of various approaches. A complete model of the three-phase unidirectional structure is presented for the purpose of design analysis. This model incorporates the effects of the electrodes and transducer pattern along with the equivalent circuit model of the transducer structure. The model, when included with the appropriate peripheral components for transducer phasing and matching, can be used to determine accurately the frequency response of a given transducer structure. Such a model is well suited for implementation on a digital computer. With this in mind, the necessary FORTRAN 77 software was developed and is presented which is an addition part of the SAW computer aided design (CAD) facilities at UCF-COE. An analysis example is given and the results are compared to published data.
