Proc. ASME. IMECE2022, Volume 5: Dynamics, Vibration, and Control, V005T07A009, October 30–November 3, 2022
Paper No: IMECE2022-96673
... Abstract Corrosion is a typical damage type in metallic structures. Free water on metallic structures can gradually lead to corrosion damage. In this study, we investigated free water sensing based on surface acoustic waves (SAWs). The fabricated SAW device consists of two interdigital...

... Abstract We theoretically investigate with the help of the finite element method, the interaction between aluminum pillars erected on top of a semi-infinite substrate of silicon in the low frequency range. Our interest is to control and manipulate the propagation of surface acoustic waves (SAW...
