Offer Description

Project context
PCs and MMs are periodic (or quasi-periodic) composites made of building blocks, i.e., unit cells, capable of performing spatial and spectral control of waves due to frequency-dependent directionality or band gap (BG) effects (i.e., frequency regions where the propagation of waves is strongly attenuated) induced by nondestructive interferences created by either the scattered wave field from periodic abrupt stiffness / mass changes (Bragg BGs) or resonating inhomogeneities (locally resonant BGs). The concept of BG naturally leads to applications involving vibrations, wave filtering and attenuation (in various frequency regimes ranging from Hz to kHz: reduction of ground motion of seismic waves, acoustic or underwater noise reduction, and reduction of vibrations, to cite a few).

Main objectives
The primary goal of this postdoctoral research is to design and manufacture new architectured phononic crystals and elastic metamaterials to control the propagation of elastic waves in solids, air, and underwater environments. Numerical analyses and experimentally characterization of the static and dynamic behavior of such architectured phononic crystals and metamaterials, as well as of biological systems characterized by a (quasi-)periodic and hierarchical arrangement, will be conducted.
Given the scalable nature of wave equations, the research will also explore applications in other domains.

Location
The Institute of Electronic, Microelectronic and Nanotechnology (UMR CNRS 8520 – https://www.iemn.fr/en/ ) is in Villeneuve D'Ascq, close to the city of Lille (France). With a total staff of over 500 people, the institute has a broad area of research activity ranging from physics to materials science, acoustics, micro- and nanotechnology.

Funding
This contract is supported by the ERC StG project POSEIDON on « Unconventional principles of underwater wave control in the sub-wavelength regime ».

Eligibility criteria

Required qualifications
The ideal candidate is required to hold a PhD in engineering, physics, or similar disciplines with advanced experience in numerical methods (FEM, BEM, …) and experimental characterization (SLDV, impedance tube, water tanks, etc.). A solid background in structural mechanics and wave propagation in periodic structures is also required. A good knowledge of modelling the interaction between solids and (heavy) fluids is also recommended.
