Context and objective of the project: Nano-opto-electro-mechanic (NOEMS) defines the field of physics in which electrons, photons (optical waves) and phonons (mechanical vibrations) can coexist and interact at the nanoscale. The interaction between these waves allows to consider functionalities that are essential in Information and Communication Technologies (ICT) systems. Particularly, the exchange of information and its processing is based on the photon-phonon interaction resulting from the coupling of a photonic fiber with a high-quality optomechanical cavity.
The objective of the Post Doc will be to realize new optomechanical devices, in relation with physical properties as topological insulator one, to study the interactions between photons and phonons, in nanobeams and membranes, and then to optimize their performances by introducing new interfaces for the conversion, storage and manipulation of information.

Main tasks and responsibilities: The candidate will work in a collaborative way in the framework of the European project HORIZON-CL4-2022-RESILIENCE-01-10 MAGNIFIC (« Materials for a next-generation (nano-)opto- electro-mechanical systems ») for broadband Access Networks. He/she will design and model phononic/photonic crystals, metamaterials and metasurfaces for 5G and SATCOM applications (i.e. opto-mechanical cavities operating between 3 - 6 GHz and 8 - 12 GHz, respectively). The unit cell architecture, size, aspect ratio, etc. will then be optimized, as well as the finite structure using analytical, semi-analytical and numerical simulations. The candidate will be expected to contribute to the analysis and interpretation of the data, the preparation of manuscripts and the dissemination of the results at national and international conferences/meetings.

Location: The Institute of Electronics, Microelectronics and Nanotechnology (UMR CNRS 8520 - https://www.iemn.fr/en/ ) is located in Villeneuve d'Ascq, near the city of Lille (France). With a total staff of more than 500 people, the institute has a wide range of research activities from physics to materials science, micro and nanotechnology. The Post Doc will be under the supervision of two teams belonging to the iemn. The Ephoni team, leaded by Pr. Y. Pennec, has a long expertise in the theoretical study of wave propagation in phononic, photonic and plasmonic nanostructures/crystals. The work will be followed also by Dr M. Miniaci from the IEMN Acoustic group. Close collaborations with and other European research groups, INL at Braga (Portugal), UPV in Valencia (Spain), VTT in Helsinki (Finland) specialized in the fabrication and characterization of micro and nano systems are also planned.

Competences The ideal candidate should have a PhD in engineering, physics or similar disciplines. Experience in numerical modelling of surface/volume elastic waves and a strong background in structural mechanics and wave propagation in periodic media are also required. A good knowledge of electromagnetism, opto-mechanical coupling and/or topological protection will be considered as a plus.
