Modeling Surface Acoustic Wave Sensors in COMSOL Multiphysics®

时长: 1:01:19
 

Watch this archived webinar, originally hosted by IEEE Spectrum, to learn how to model surface acoustic wave (SAW) sensors in the COMSOL Multiphysics® software. Guest speaker David Greve of DWGreve Consulting discusses the application and design of SAW sensors and demonstrates how to simulate changes in acoustic surface wave velocity due to changes in the overlayer. An eigenfrequency analysis of surface wave modes is performed to derive the acoustic wave velocity.
