Finite Element Model of Surface Acoustic Wave Scattering with High-Aspect-Ratio Irregularities
Publié en 2016
The design of surface acoustic wave (SAW) devices needs the accurate study of the scattering fields, arising from the interaction of SAW with periodic irregularities placed on a surface of crystal to form interdigital transducers or reflective structures (RS). To solve this problem, the finite element methods are very perspective, because they allow to take into account the actual geometry of the electrodes and bulk scattering, in contrast to analytical methods.
