According to a study from Cambridge, Canada, "The Green's function or boundary element method (BEM) is the best available technique for rigorous surface acoustic wave (SAW) device analysis. However, its computational cost usually means that it cannot be applied directly to devices with complex, nonperiodic electrode structures."
"In this paper, approximate forms for the Green's function are employed. They are based on rigorous representations, they can represent the Greens function to any required degree of accuracy, and they can be applied to any type of substrate and acoustic wave. The use of this type of approximation for practical device analysis is ...
