Frequency Domain Modeling of SAW Devices

چکیده
New SAW sensors for integrated vehicle health monitoring of aerospace vehicles are being investigated. SAW technology is low cost, rugged, lightweight, and extremely low power. However, the lack of design tools for MEMS devices in general, and for Surface Acoustic Wave (SAW) devices specifically, has led to the development of tools that will enable integrated design, modeling, simulation, analysis and automatic layout generation of SAW devices. A frequency domain model has been created. The model is mainly first order, but it includes second order effects from triple transit echoes. This paper presents the model and results from the model for a SAW delay line device.

متن کاملFinite element modeling of acoustic streaming in SAW devices
Fluid motion induced from high intensity sound waves is called acoustic streaming. SAW devices used in biological species detection suffer from fouling that results from binding of non-specific protein molecules to the device surface. The acoustic streaming phenomenon can be used to remove these non-specifically bound proteins to allow reuse of SAW devices. A finite element model of acoustic st...
