The postdoctoral researcher will be part of the SWAP theme (Subwavelength Physics) at the Langevin Institute devoted to the study of wave phenomena occurring at a subwavelength scale. More specifically, the postdoctoral researcher will join the team of Fabrice Lemoult (email@example.com) who is interested in electromagnetic and acoustic metamaterials. The requested work will be part of the ANR Meta-Foret project (http://metaforet.osug.fr) which studies the propagation of seismic waves in a forest that typically plays the role of a metamaterial.
The Meta-Foret project is interested in studying the propagation of seismic waves within a forest. Each tree plays the role of a resonator that is coupled to the waves propagating in the soil through its foot. In the context of this project, it has been shown that the forest acts as a macro-metamaterial for seismic waves, notably with the appearance of a forbidden band for the propagation of certain seismic waves. Here, we are more interested in laboratory experiments. In particular we will study the influence of acoustic coupling between trees through the waves propagating in the air.
The candidate needs a PhD degree and experience in the field of metamaterials (acoustic or electromagnetic). He/she must have a knowledge in the field of elastic waves. An experimental know-how is required in order to carry out such an experiment in a relatively short period of time. Knowing how to use numerical simulation software based on finite elements is also required. A relative autonomy will be greatly appreciated.
The Langevin Institute is a Joint Research Unit (UMR 7587) of ESPCI Paris and CNRS dedicated to wave physics and its applications. Researchers at the Institute aim to understand the mechanisms of the propagation of different types of waves (mechanical and electromagnetic) in complex environments and to take advantage of this better understanding to design original instruments for the manipulation of these waves. In 2011, the Langevin Institute obtained the label LabEx (laboratory of excellence) for its project WIFI (Waves and Imaging: from Fundamentals to Innovation).
