Dynamical study of mechanical metamaterials for ultrasonics

Contact: Muamer Kadic at

and Vincent Laude at

Description (starting October 2019): 

Manufacturing will be performed by additive manufacturing, either by 3D printing or by direct laser writing by two-photon photopolymerization, depending on the target frequency range. The behavior of the phononic structures will be characterized by using a MEMS analyzer and by ultrasonic measurements to determine acoustic velocities as a function of the direction of propagation. The design will be based on the analysis of the homogenized properties of metamaterials and on the technique of space transformation. Modeling will be carried out by finite element analysis of the properties of a unit cell or a complete structure.
