Thèse convention CIFRE : active metasurfaces for automotive applications – Valeo (Bobigny) / C2N (Palaiseau)

This PhD thesis has the ambition to develop large-diameter metasurfaces with high resolution and performance operating in the visible light range. A metasurface is made of subwavelength metallic or dielectric nanostructures whose shape and arrangement enables light to be focused and/or filtered. The interaction with light is due either to plasmonic resonances (metallic nanostructures) or […]

3 PhD opportunities on reconfigurable directive antennas, France, from October 2023

In the framework of a national project on reconfigurable directive antennas, key academic French Research laboratories (CEA LETI, ICMCB, IETR, Telecom Paris and XLIM) are joining forces to propose innovative architectures for reconfigurable low-profile and highly directive antennas to go beyond the current state of the art. In this framework, three PhD positions are proposed […]

PhD offer, LOMA, Bordeaux: Design and characterisation of new laser sources based on Organic Light Emitting Transistors

The first objective is to study and optimize the light confinement induced by Bragg gratings such as Distributed Bragg Reflectors (DBR) and Distributed FeedBack structures, inserted in OLETs. Quantitative calculations will be done, using several existing numerical tools (Transfer Matrix Method, Finite Element Method, Fourier Methods), to simulate exciton emission in the 3D non-planar multilayer […]

Six PhD offers for the GENIUS MSCA Doctoral Network – « Glide-symmetric metasurfaces for communications and sensing »

Metamaterials characterized by glide symmetries possess marvellous electromagnetic properties (ultra- wide band propagation, strong isolation and high absorption features) capable to address the open challenges of modern radio-frequency systems, motivated by the increasing demand of ubiquitous connectivity, and the growing automation of transports. The six doctoral students recruited in this doctoral network will work on […]
