We introduce the concept of transformation crystallography which consists of the application of geometric transforms to periodic structures. We consider motifs with three-fold, four-fold and six-fold symmetries according to the crystallographic restriction theorem. Furthermore, we define motifs with five-fold symmetry such as quasi-crystals generated by a cut-and-projection method. We analyze elastic wave propagation in the transformed crystals and (Penrose-type) quasi-crystals with the finite…

Metamaterial-like transformed urbanism

Viewed from the sky, the urban fabric pattern appears similar to the geometry of structured devices called metamaterials; these were developed by Physicists to interact with waves that have

Contrôle de la diffusion par des façades : cas des métasurfaces et des guides d'ondes ouverts inhomogènes

L’objectif de ce travail est le developpement de dispositifs de controle de la diffusion des ondes acoustiques a l’aide de surfaces heterogenes, pour des applications a l’acoustique urbaine. Pour



Experiments on seismic metamaterials: molding surface waves.

For complex natural materials such as soils, this large-scale experiment was needed to show the practical feasibility of seismic metamaterials and to stress their importance for applications in civil engineering.

A seismic metamaterial: The resonant metawedge

The efficiency of the resonant metawedge shows that large-scale mechanical metamaterials are feasible, will have application, and that the time is ripe for considering many optical devices in the seismic and geophysical context.

Large scale mechanical metamaterials as seismic shields

Earthquakes represent one of the most catastrophic natural events affecting mankind. At present, a universally accepted risk mitigation strategy for seismic events remains to be proposed. Most

Controlling solid elastic waves with spherical cloaks

We propose a cloak for coupled shear and pressure waves in solids. Its elastic properties are deduced from a geometric transform that retains the form of Navier equations. The spherical shell is made

Forests as a natural seismic metamaterial: Rayleigh wave bandgaps induced by local resonances

The thesis that resonances in trees result in forests acting as locally resonant metamaterials for Rayleigh surface waves in the geophysics context is explored and bandgaps generated by the coupling of the successive longitudinal resonances of trees with the vertical component of the Rayleigh wave are explored.

Elastic metamaterials with inertial locally resonant structures: Application to lensing and localization

We propose a type of locally resonant structure involving arrays of structured coated inclusions. The coating consists of a structural interface with beams inclined at a certain angle. Such an

Harnessing buckling to design tunable locally resonant acoustic metamaterials.

A new class of tunable and switchable acoustic metamaterials comprising resonating units dispersed into an elastic matrix, whose buckling is intentionally exploited as a novel and effective approach to control the propagation of elastic waves.

On cloaking for elasticity and physical equations with a transformation invariant form

In this paper, we investigate how the form of the conventional elastodynamic equations changes under curvilinear transformations. The equations get mapped to a more general form in which the density

Achieving control of in-plane elastic waves

We derive the elastic properties of a cylindrical cloak for in-plane coupled shear and pressure waves. The cloak is characterized by a rank 4 elasticity tensor with spatially varying entries, which
