Abstract :
A general finite difference technique is described for the AC steady-state analysis of two-dimensional piezoelectric devices. The method is formulated to accommodate anisotropic and inhomogeneous material as well as variable mesh spacings such that irregular boundaries can be modeled. The method is applied to a bulk acoustic wave resonator and stacked crystal filter structures. For the resonator analysis, the results are compared with published data
