If you are interested in modeling surface acoustic wave (SAW) sensors, then tune into this webinar with guest speaker David Greve of DWGreve Consulting.
SAW devices with a chemical-sensing overlayer provide for the selective sensing of particular gases. Sensing takes place due to electrical conductivity and mass density changes of the overlayer that change the propagation velocity of acoustic surface waves.
In this webinar, we will show how the COMSOL Multiphysics® software supports the design of SAW sensors by simulating the changes in the acoustic surface wave velocity due to changes in the overlayer. You will see a live demonstration of how to perform an eigenfrequency analysis of surface wave modes and derive the acoustic wave velocity, including how to specify model settings such as boundary conditions and material properties.
You can ask questions at the end of the webinar during the Q&A session.
