Topics of Research
The “metamaterial” concept has expanded rapidly over the past decade. It was first applied in electromagnetism and optics, where the structuring of matter at a length scale smaller than the considered wavelength allowed obtaining outstanding properties. For example, it has been possible for the first time to manufacture materials that have a negative refractive index or a magnetic response in the optical spectral range. These advances have opened the way to applications that were previously unthinkable, such as the “superlens” (a lens that can beat the diffraction limit), the invisibility cloak or the perfect absorber. Furthermore, the concept of “metamaterial” has recently been extended to thermodynamics, acoustics and mechanics, which widens the field of possibilities.
Since its creation, the LSFC has developed a strong expertise in the field of materials with multi-scale architectures. In continuation of this work, my aim is to develop a new research axis focused on the realization of ceramic metamaterials. The objective is to take advantage of the excellent intrinsic properties of technical ceramics, such as their resistance to high temperatures and to combine them with innovative concepts derived from metamaterials, in order to manipulate their mechanical, optical and thermal properties.
