Abstract
A method of simulating a surface acoustic wave (SAW) on a structure that is modeled on a computer or other processor-based device enables the testing of actual SAW devices or to develop improved SAW devices. In this method, the modeled structure is preferably that of a corrugated structure that includes an electrode disposed on top of a piezoelectric substrate. A meshfree method then is applied to the modeled structure using Newton's equation of motion and Gauss's equation of charge conservation as governing equations. Subsequently, a set of equations is solved simultaneously to obtain numerical results.
