This fully funded PhD position at the University of Rennes (IETR, UMR CNRS 6164) in France focuses on the analysis and design of advanced electromagnetic (EM) periodic structures—such as metasurfaces and dichroic devices—for next-generation space applications. The project is a collaboration between IETR, CNRS, and the French Space Agency (CNES), and aims to push the boundaries of electromagnetic design for satellite communications and Earth observation systems.

The research will address the challenges of developing low-profile, lightweight, and cost-effective hardware for space-borne systems, with a particular emphasis on polarization converters, broadband antennas, and dichroic devices operating at K/Ka bands. The project will leverage artificial intelligence (AI) to optimize the design and analysis of these complex EM structures, drastically reducing simulation time and enabling rapid exploration of large design spaces. The synergy between AI and EM is crucial for modern space communications and environmental monitoring, as more than 50% of climate variables can only be measured from space.

The PhD student will work on electromagnetic modeling, full-wave simulation, advanced antenna design, manufacturing, and experimental validation. The research program is structured into five main stages: literature review, development of AI-based design frameworks, design and prototyping of dual-band polarization converters and dichroics, and experimental characterization using IETR's state-of-the-art facilities (NanoRennes and M²ARS platforms).

Applicants should have a strong background in electromagnetics, microwave engineering, antenna theory, and periodic structures, with proficiency in English. The position is open to candidates with a Master's degree or equivalent in electrical engineering or physics. The project offers a gross monthly salary of 2300 €, 44 days of annual leave, partial transport cost coverage, and remote working options. The application window is from February 2 to March 13, 2026, with the position starting in September 2026. For more information, candidates can contact the supervisors or visit the provided links.
