    • Cantilever Beam Metastructure for Active Broadband Vibration Suppression 

      Ghachi, Ratiba Fatma; Alnahhal, Wael; Abdeljaber, Osama ( Qatar University Press , 2020 , Poster)
      This paper presents a beam structure of a new metamaterial-inspired dynamic vibration attenuation system. The proposed experimental research presents a designed cantilevered zigzag structure that can have natural frequencies ...

    • Wave Propagation Identification of Viscoelastic and Metallic Mechanical Metamaterials 

      Ghachi, Ratiba Fatma (2021 , Dissertation)
      Mechanical Metamaterials (MMs) are artificially engineered composites which have unconventional mechanical properties that stem from their microstructural geometry rather than from their chemical composition. Several studies ...
