[EN] The optimal absorption of flexural energy by the critical coupling of a locally resonant grating embedded in a thin plate is reported in this work for the reflection and transmission problems. The grating is made of ...
[EN] It has been shown that the photonic bandgap of one-dimensional (1D) dielectric periodic thin films can vanish at the first Bragg condition for TM modes. Here, we address the case of 1D photonic crystal slabs formed ...

Coupling of Rayleigh waves propagating along two metal surfaces separated by a narrow fluid channel is predicted and experimentally observed. Although the coupling through a fluid (water) is weak, a strong synchronization ...
[EN] Most simulations involving metamaterials often require complex physics to be solved through refined meshing grids. However, it can prove challenging to simulate the effect of local physical conditions created by said ...
[EN] A hexagonal array of parallel circular cylinders embedded in a matrix is considered. The fibers are filled with a transversely isotropic (TI) elastic material whereas the matrix material is an ideal fluid. The asymptotic ...

[EN] The goal of this thesis is to present a preliminary study into developing damage resistant
peristalitic gaits in soft robotic matter. To do so, we’ll explore ways to simulate, control
and design soft robotic matter: ...
[EN] By studying platonic crystals based on lattices of cavities containing N-beam resonators, we conclude that crystals made of 1-beam resonators easily produce low-frequency omnidirectional bandgaps. Based on this favorable ...
[EN] In this work, we show that scattered acoustic vortices generated by metasurfaces with chiral symmetry present broadband unusual properties in the far-field. These metasurfaces are designed to encode the holographic ...

[EN] Over the last decade, negative index media have attracted much attention due to their potential applications, especially the possibility of constructing superlenses. However, achieving high-performance negative-index ...
In this work, we present a metamaterial working at terahertz frequencies made over a flexible polypropylene sub-strate. The experimental measurements, in accordance with the numerical calculations, show the metamaterial ...

We apply a homogenization process to the acoustic velocity potential wave equation. The study of various
examples shows that the resulting effective properties are different from those of the homogenized pressure
