Abstract：

I will provide an overview on recent researches on acoustic and elastic metamaterials and metasurfaces for sound/vibration isolation and acoustic energy harvesting we are developing in our group in the University of Lorraine. I first will present some advances related to low-frequency acoustic and vibration shielding/absorption making use of metamaterials1,2 and metasurfaces3,4, and describe the added value that such artificial engineered materials can bring to consider some innovative applications. Findings on both acoustic and elastic waves will be presented. Second, I will introduce and delineate the concept of acoustic energy harvesting based on metamaterials5 and metasurfaces6, the associated configurations and designs and the expected functionalities. The purpose of this seminar is to highlight the new properties/functionalities and applications the metamaterials in general are enabling and the emerging concrete applications they are generating.
