Sh wave finite element
WebThe Wave Finite Element Method The Wave Finite Element method basically is a technique to investigate wave motion in both periodic structures or continuous waveguides in 1 dimension (e.g. beams) and 2 dimensions (e.g. plates), [1,2]. In this method a “period” of the structure is modelled using conventional FEs. The equation of motion for WebThis paper presents the 3-dimensional finite element (FE) modeling and simulation results for a SH-SAW device using CoventorWaretrade (CW). The substrate used is 64deg rotated Y-cut LiNbO 3 with Au/Cr Interdigital Transducers (IDT) having a periodicity of 40 mum. 3D transient analysis was performed on the devices to study the acoustic wave propagation …
