Context High gain electronically reconfigurable antennas with beam-steering, multi-beam, and beam-forming capability are required in a huge number of emerging applications for radar, sensing, and communication systems (civil and military) typically ranging from C-band (4-8 GHz) to D-band (110-170 GHz). Classically composed of one or more radiating surfaces operating in transmission mode and illuminated by […]

PhD offer: Millimeter-wave technologies for biomedical electromagnetics : multi-physics microdosimetry
Context Millimeter-wave (MMW) technologies are increasingly used for various applications. In particular, they have been used for high data rate communications [> 5 Gb/s] and 60-GHz technologies are expected to be integrated in the near future in the next generation mobile systems. Besides, it was suggested that MMW can be used for a number of […]
PhD offer: Modeling and characterization of high-speed interconnects (antennas and transmission lines) at millimeter waves for automotive applications
Context APTIV is a high-technology company that integrates safer, greener and more connected solutions for the automotive and transportation sectors. To fulfill the needs of our R&D center located in Epernon, France, we are looking for a candidate to prepare a PhD thesis on high-speed transmissions at millimeter waves. Description You will be recruited for […]
PhD offer: Fast and Accurate Iterative Physical Optics Approach for the Modeling of Electrically Huge Platforms
Context The Iterative Physical Optics (IPO) is a High Frequency method for the electromagnetic analysis, which is inherently parallelizable, thus providing an unrivaled fast tool for the description of large platforms, prediction of RCS, antenna siting, etc. Since based on Physical Optics approximation, though augmented by its iterative scheme, IPO is an approximate method that […]

PhD offer: Universal Launcher Antenna
Context Communication links onboard launchers consist in 3 main functions: Telecommand, Trajectography and Telemetry. Each function currently operates over a dedicated frequency range within [0.4 GHz ; 6 GHz] and a specific antennas network is used for each one via different concepts. Such an implementation is not optimal from an industrial point of view since […]
Offre de thèse : Approches optique-hyperfréquences pour l’imagerie polarimétrique et la physique de la dépolarisation lumineuse
Contexte L’imagerie polarimétrique est une technique d’imagerie non conventionnelle qui consiste à mesurer l’état de polarisation de la lumière rétro-diffusée par un objet en tout point de l’image et à analyser le comportement polarimétrique des objets imagés. Ce type d’imagerie trouve des applications de plus en plus nombreuses, par exemple pour la microscopie (diagnostic/suivi de […]
Offre de thèse : Télédétection pour la caractérisation et la quantification de pollution marine – étude de la complémentarité radar / optique
Contexte Les données de télédétection aéroportées et/ou satellitaires sont communément utilisées pour détecter, caractériser et quantifier des produits déversés sur la surface océanique. De façon opérationnelle, l’imagerie radar est habituellement employée dans une première phase de détection de la nappe formée par le produit à large échelle ; l’imagerie optique vient ensuite pour caractériser (nature) […]
PhD offer: Low profile and broadband antennas for high speed wireless at 300 GHz
Context A more efficient use of available spectrum does not suffice to reach the ultra-large bandwidths (BWs) required by wireless systems beyond 5G, and the use of frequencies in the Terahertz (THz) gap is the key to enable ultra-large BW wireless. The frequency range between 275 and 350 GHz is particularly convenient, owing to the […]
PostDoctoral offer: Low-profile steerable antenna in Ka-band
Context Institut d’Électronique et de Télécommunications de Rennes (IETR), UMR CNRS 6164. Rennes, France. Overview Compact and efficient antenna architectures are key enabler solutions for on-board electromagnetic applications (telecommunications, radars, electronic warfare, etc.). Current solutions use cumbersome mechanical systems, or expensive but flat electronically steered phased arrays. High data rates require the large bandwidth available […]
