Abstract :
The Green´s function method is generally agreed to be the most satisfactory technique for the rigorous analysis of surface-acoustic-wave interdigital transducers (IDTs). However, its direct application to response investigations or optimization-based design activities is limited by its computational complexity. In this paper, we present a new reduced-order model of IDTs based on a moment-matching technique and on the singular value decomposition. Several numerical and experimental examples demonstrate the accuracy and the efficiency of the method
