Abstract
The characterization of fi nite length Surface Acoustic Wave (SAW) and Bulk acoustic Wave (BAW) resonators is ad dressed here. The Finite Element Analysis (FEA) induces arti fi cial wave re fl ections at the edges of the mesh. In fact, these ones do not contribute in practice to the corresponding experimental response. The Perfectly Matched Layer (PML) method, allows to suppress the boundary re fl ections. In this work, we fi rst demonstrate the basis of PML adapted to FEA formalism. Next, the results of such a method are depicted allowing a discussion on the behavior of fi nite acoustic resonators.
