GRIDS-Net: Inverse shape design and identification of scatterers via geometric regularization and physics-embedded deep learning
Siddharth Nair, Timothy F. Walsh, Greg Pickrell +1
This study presents a deep learning based methodology for both remote sensing and design of acoustic scatterers. The ability to determine the shape of a scatterer, either in the co…
Nonlocal elastic metasurfaces: enabling broadband wave control via intentional nonlocality
Hongfei Zhu, Timothy F. Walsh, Bradley H. Jared +1
While elastic metasurfaces offer a remarkable and very effective approach to the subwalength control of stress waves, their use in practical applications is severely hindered by in…
Total-internal-reflection elastic metasurfaces: design and application to structural vibration isolation
Hongfei Zhu, Timothy F. Walsh, Fabio Semperlotti
This letter presents the concept of Total Internal Reflection metasurface (TIR-MS) which supports the realization of structure-embedded subwavelength acoustic shields for elastic w…
