General information

Reference : UMR8520-FRELEF-137
Workplace : LILLE
Date of publication : Thursday, November 10, 2022
Type of Contract : FTC Scientist
Contract Period : 12 months
Expected date of employment : 2 January 2023
Proportion of work : Full time
Remuneration : From 2833,40 euros gross salary per month
Desired level of education : PhD
Experience required : Indifferent


The candidate will perform her / his research supervised by Dr. Marco Miniaci, in the framework of the FET-OPEN research project BOHEME on « Bio-inspired hierarchical metamaterials »


She / he will investigate phononic crystals and metamaterials mainly in the context of airborne acoustics, although she / he may also be involved in metamaterial applications in other frequency ranges. Collaborations with foreign renowned research groups is foreseen (Imperial College of London, Politecnico di Torino, ETHZ, Empa, etc.) as well as with industrial partners (Multiwave and Phononic Vibes). The candidate is expected to contribute on the analysis and interpretation of data, manuscript preparation and dissemination of the results in the context of national and international conferences/meetings.


Candidates are required to hold a PhD in engineering, physics, or similar disciplines. A solid background in airborne acoustics and wave propagation in periodic media, phononic crystals and metamaterials is required. Experience in experimental measurements of acoustic / elastic wave propagation is a valuable plus, as well as experience in analytical and numerical methods (MS, FEM, BEM, ...).

Work Context

Airborne noise insulators capable of broadband good performances in the sub-wavelength frequency regime is a fundamental problem of interest in many disciplines ranging from physics to engineering. Metamaterials, which are composite structures made of periodic unit cells performing spatial and spectral control of waves due to a frequency-dependent directionality or band gap (BG) effects, are more and more used as an innovative solution to mitigate and control sound and vibrations in general.
In this context, our assumption is that the working principle behind metamaterials is already exploited by Nature, where it has given rise to goal-oriented optimized designs, due to the evolutionary development process, including optimized designs for wave and vibration control. The main objective of the postdoc position is to conceive, manufacture and experimentally characterize an innovative metamaterial inspired by biological systems to create an innovative lightweight and compact noise insulation screen (operating at the sub-wavelength regime). Due to the scalability of the wave equations, other domains of applications will be also investigated.
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 persons, the institute has a broad area of research activity ranging from physics to materials science, acoustics, micro- and nanotechnology. The laboratory of Acoustics (where the candidate will have her / his office) is in the city center of Lille (41 Boulevard Vauban), within the « Junia » buildings.
