Presentation of the team
Attached to the Department 'Antennas & Microwave Devices' (ADH), the FunMAT team is composed of teacher-researchers and researchers combining multidisciplinary and complementary scientific skills in the specialty "Materials / STIC" (CNU sections 28, 31, 33 and 63, and section 14 of the CNRS)
The research activities cover all aspects, from fundamental research on materials with particular properties up to the evaluation of the performance of especially developed demonstrator devices. The work is more particularly oriented to the development and mastery of the different functional materials' properties developed within the Team and is about:
non-linear piezoelectric and ferroelectric properties of ceramics or thin film oxides and oxynitrides,
the association of optical transparency / electrical conductivity in thin films,
the electrostriction of polymers
the reactivity and chemical selectivity of organic materials
electromagnetic absorption as well as control of electric / dielectric surfaces and interfaces of monolithic, sandwich and / or extruded composite materials.
The fundamental understanding of the functional characteristics of the developed materials, as well as their implementation is at the heart of the team's expertise. The work undertaken covers the microscopic description and interpretation of the phenomena observed up to the optimization of its properties, by developing suitable characterization techniques.
Promoting the application potential of the different material classes studied, the work is divided into 4 main thematics:
Miniaturization and reconfigurability
Active communicating surfaces
Energy recovery and storage
The co-design of Materials / Devices is an undeniable advantage in the development of futur communicating systems, as well as its associated networks. In addition to the scientific advances made in many electronic devices and antenna systems developed with the functional materials , this research opens up new perspectives in other application fields, related to the energy, health, housing, transport and defense sectors.
This work is carried out in close collaboration with the WAVES, CUTE and BEAMS teams of the ADH department. The FunMAT team is located in 3 of the 8 geographic sites of the IETR: Saint-Brieuc, Rennes and Nantes.
The research engaged by FunMAT relies on a coherent set of equipments available from the technical platform MATRIX. This platform is expanding due to the acquisition of new elaboration and characterization means via the projects CPER MATECOM and SOPHIE / STIC & Ondes [2015-2020], as well as via the RFI WISE of the West Electronique Network (Wen) in the region "Pays de la Loire".
