\nAbstract: I will 
 provide an overview on recent researches on acoustic and elastic metamater
 ials and metasurfaces and their applications including sound/vibration iso
 lation\, asymmetrical propagation and acoustic energy harvesting. I first 
 will introduce and delineate the general concepts of acoustic metamaterial
 s 1\,2 and metasurfaces 3\,4\, their properties and functionalities. Then\
 , I will detail some specific applications related to low-frequency acoust
 ic shielding/absorption\, controllable wave manipulation\, and describe th
 e added value such artificial engineered materials can bring to deal with 
 technological challenges. The purpose of this seminar is to highlight the 
 new properties/functionalities and applications the metamaterials and meta
 surfaces can produce\, and the emerging pragmatic applications they can ge
 nerate.

\nBio: Badreddine Assouar received his Ph.D. degree in Materials Physi
 cs from Nancy University in France in 2001. In 2002\, he became a Research
  Scientist at the “Centre National de la Recherche Scientifique (CNRS)
 ” in France. He obtained his Habilitation to supervise research (HDR) in
  2007 and became a Research Professor. In 2010\, he joined Georgia Institu
 te of Technology in the USA as Visiting Professor\, where he spent two yea
 rs. Since 2012\, he leads the “Acoustics Metamaterials and Phononics” 
 group at the University of Lorraine\, where he is developing researches on
  acoustic/elastic metamaterials\, metasurfaces\, and phononics. B. Assouar
  is Associate Editor of “Phys. Rev. Applied”\, “JASA”\, and Editor
 ial Board Member of “J. Appl. Phys”. He is also an expert scientist wi
 th the National Science Foundation (NSF USA). He is author or co-author of
  more than 100 international peer-reviewed international publications. His
  research interests are in the areas of acoustic and elastic metamaterials
 \, metasurfaces\, phononics and energy harvesting.
