Abstract
The present disclosure provides systems and methods for hierarchical cascading in finite element method (FEM) simulations of surface acoustic wave (SAW) devices, which offers drastically reduced memory consumption and simulation times. In some implementations, iterative hierarchical cascading may also be applied to three-dimensional simulations of SAW devices, which may otherwise be too complex for FEM simulations due to the high number of cross-sectional degrees-of-freedom involved.
