[PhD] Acoustic metamaterials for sound transmission cancellation (Univ. Le Mans, France)

Application deadline: Wed 05 Apr 2023

Expected starting date: October 1st 2023

Application Deadline: April 5th 2023


This doctoral project is part of a larger, multidisciplinary and international project

METAVISION: “METAmaterials for VIbration and Sound reductION” (no. 101072415)

funded under the Marie-Sklodowska-Curie Actions Doctoral Networks within the

Horizon Europe Programme of the European Commission.

METAVISION aims to reconcile two conflicting trends. On the one hand, people

become increasingly aware of the negative health impact of excessive noise and

vibration exposure. On the other hand, every kilogram of mass removed from the

logistics chain has a direct economic and ecological benefit. Current noise and

vibration solutions still require too much mass or volume to be practically feasible,

particularly for lower frequencies. There is thus a strong need for low mass, compact

material solutions with excellent noise and vibration characteristics, for which recently

emerged so-called metamaterials have shown immense potential. METAVISION

aims to develop novel design and analysis methods in view of broadening the

performance and applicability of metamaterials, revolutionize the manufacturing of

metamaterials towards large-scale and versatile solutions and advance academically

proven metamaterial concepts towards industrially relevant applications.

METAVISION gathers universities (KU Leuven, Université du Mans, Universidade de

Coimbra), research institutes (Centre National de la Recherche Scientifique, Swiss

Federal Laboratories for Materials Science and Technology EMPA) and small- and

large-scale industry (Siemens Industry Software NV, Materialise NV, MetAcoustic,

Phononic Vibes srl, Airbus, Swiss Federal Railways, Mota-Engil Engenharia e

Construção S.A.) from manufacturing , construction, transportation, machine design

and noise and vibration solution sectors with the relevant expertise to create the

coordinated research environment needed to bring metamaterials from academic

concepts to large-scale manufacturable and industrially applicable noise and

vibration solutions, paving the way towards a quieter and greener Europe.

Your tasks

As doctoral candidate within this project you will work on the design, manufacturing,

and experimental validation of acoustic metamaterials for sound transmission

cancellation. To do this :

  • You investigate different design strategies
  • You investigate potential optimization strategies
  • You design and measure prototypes to validate the models
  • You identify the ideal solution for specific problems.

Profile :

If you recognize yourself in the story below, then you have the profile that fits the

project and the research group:

  • I have a master degree in acoustic, physics, mechanical engineering or

mathematics, obtained no longer than four years ago and performed above

average in comparison to my peers.

  • I am proficient in written and spoken English.
  • I have not had residence or main activities in France for more than 12 months

in the last 3 years.

  • During my courses or prior professional activities, I have gathered some

experience with at least one of the following: principles of acoustics, numerical

modeling techniques, or experimental methods in acoustics. I have a profound

interest for these topics.

  • As a researcher I perform research in a structured and scientifically sound

manner. I read technical papers, understand the nuances between different

theories and implement and improve methodologies myself.

  • In frequent reporting, varying between weekly to monthly, I show the results

that I have obtained and I give a well-founded interpretation of those results. I

iterate on my work and my approach based on the feedback of my supervisors

which steer the direction of my research.

  • It is important for me to work as an active team member and I am eager to

share my results to in-spire and being inspired by my colleagues.

  • During my PhD, I want to grow towards following up the project that I am

involved in and representing the research group on project meetings and

conferences. I see these events as an occasion to disseminate my work to an

audience of international experts and research colleagues, and to learn about

the larger context of my research and the research project.


We offer a fully funded 3-year PhD position at LAUM, UMR 6613 CNRS. Perfect

absorption of acoustic waves has been the focus of numerous studies this last

decade. Several design strategies have been proposed to achieve perfect absorption

either focusing on the subwavelength or on the broadband aspects. In this PhD, you

will focus on transmission cancellation, that is the total annihilation of the acoustic

wave energy. Various strategies, involving non-reciprocal features, will be

investigated and combined.

For further information about the position please contact Vincent Pagneux ( Vincent.Pagneux@univ-lemans.fr), Vicente Romero-García (virogar1@upvnet.upv.es), or Jean-Philippe Groby (Jean-Philippe.Groby@univ-lemans.fr)

We look forward to receiving your online application including a letter of motivation,

CV, diplomas with transcripts and contact details of two referees.
