Effective and rapid technique for temporal response modeling of surface acoustic wave interdigital transducers
چکیده انگلیسی


- A simulation tools based on Spatial Impulse Response model and Discrete Representation Approach.
- An effective and rapid technique for SAW-IDT modeling.
- The method requires less computer memory.
- The results obtained show a good concordance with FEM simulation results and experimental results.

Surface Acoustic Wave Interdigital Transducers (SAW-IDT) has a considerable application potential for characterization of properties of thin layers, coatings and functional surfaces. For optimization of these SAW-IDTs, it is necessary to study various SAW-IDT configurations by varying the number of electrodes, dimensions of the electrodes, their shapes and spacings. The finite element method (FEM) is generally used to model such transducers but results are obtained in several hours (or days). Thus it is necessary to implement effective and rapid technique for SAW-IDT modeling. In this study, we develop simulation tool based on Spatial Impulse Response model. Therefore, we reduce considerably computing time and results are obtained in a few seconds. In order to validate this method, theoretical and experimental results are compared with finite element method. The results obtained show a good concordance and confirm effectiveness of suggested method. In additional, this method requires less computer memory.
