    • Elastic metamaterials for tuning circular polarization of electromagnetic waves 

      Zárate, Yair; Babaee, Sahab; Kang, Sung H.; Neshev, Dragomir N.; Shadrivov, Ilya V.; Bertoldi, Katia; Powell, David A. (Nature Publishing Group, 2016)
      Electromagnetic resonators are integrated with advanced elastic material to develop a new type of tunable metamaterial. An electromagnetic-elastic metamaterial able to switch on and off its electromagnetic chiral response ...

    • Hierarchical honeycomb auxetic metamaterials 

      Mousanezhad, Davood; Babaee, Sahab; Ebrahimi, Hamid; Ghosh, Ranajay; Hamouda, Abdelmagid Salem; Bertoldi, Katia; Vaziri, Ashkan (Nature Publishing Group, 2015)
      Most conventional materials expand in transverse directions when they are compressed uniaxially resulting in the familiar positive Poisson’s ratio. Here we develop a new class of two dimensional (2D) metamaterials with ...

    • Honeycomb phononic crystals with self-similar hierarchy 

      Mousanezhad, Davood; Babaee, Sahab; Ghosh, Ranajay; Mahdi, Elsadig; Bertoldi, Katia; Vaziri, Ashkan (American Physical Society (APS), 2015)
      We highlight the effect of structural hierarchy and deformation on band structure and wave-propagation behavior of two-dimensional phononic crystals. Our results show that the topological hierarchical architecture and ...

    • Reconfigurable origami-inspired acoustic waveguides 

      Babaee, Sahab; Overvelde, Johannes Tesse bastiaan; Chen, Elizabeth R.; Tournat, V.; Bertoldi, Katia (American Association for the Advancement of Science (AAAS), 2016)
      We combine numerical simulations and experiments to design a new class of reconfigurable waveguides based on three-dimensional origami-inspired metamaterials. Our strategy builds on the fact that the rigid plates and hinges ...

    • Wave propagation in cross-linked random fiber networks 

      Babaee, Sahab; Shahsavari, A. S.; Wang, Pai; Picu, R. C.; Bertoldi, Katia (AIP Publishing, 2015)
      We numerically investigate the propagation of small-amplitude elastic waves in random fiber networks. Our analysis reveals that the dynamic response of the system is not only controlled by its overall elasticity, but also ...
