Missions
A one-year resercher position is available at the LMA. The mission is to study theoretically the propagation of acoustic waves in complex environments, and in particular the evidence of the phenomenon of anti-localization.
Activités
The project consists in developing an analytical and/or numerical approach to understand changes in wave propagation in a two-dimensional periodic medium perturbed by weak disorder. In two dimensions, disorder usually induces wave localization: propagative waves become evanescent. However, some two-dimensional systems have anomalous behavior at low disorder: propagation is favored by disorder rather than impeded.
The aim of this project will be to determine which acoustic configurations allow this phenomenon to be observed.
Compétences
The person recruited must hold a doctoral degree. A good theoretical knowledge of metamaterials/phononic crystals is expected, or in topological insulators and/or localization of Anderson.
Contexte de travail
The project will take place at the Laboratory of Mechanics and Acoustics (LMA), a joint research unit AMU-CNRS-Centrale Mediterranean, UMR 7031. Its main areas of expertise are the mechanics of solids (structures, materials, interfaces) and acoustics (propagation of waves in complex fluid and solid environments).
