Abstract :
Past efforts for modeling the massloading effects in surface acoustic wave devices may be classified in five groups: (i) models based on the perturbation theory, (ii) mode matching techniques, (iii) methods employing the finite element method, (iv) hybrid techniques which combine the boundary element method with the finite element method, and finally, (v) methods relying on an eigenform formulation involving coordinate-dependent coefficients. In this paper we review some of these techniques and briefly discuss our recent progress in analyzing the massloading effects in surface acoustic wave devices
