Presentation of the team

The research activities of WAVES team are focused on interactions of electromagnetic waves with complex media in various contexts. The two main research topics of the team are:

(1) Biomedical electromagnetics: innovative biomedical applications of electromagnetic fields and associated technologies.

(2) Electromagnetic compatibility: advanced numerical and experimental tools for electromagnetic compatibility testing.

Our activities in bioelectromagnetics cover a wide spectrum of fundamental and applied research spreading from multi-physics and multi-scale modeling to advanced technologies for body-centric wireless communications. The team was at the origin of pioneering innovations in biomedical electromagnetics, including the first mm-wave tissue-equivalent phantoms, novel reflectivity based surface phantom concept, new broadband multi-physics characterization technique for Debye-type materials, innovative mm-wave textile antennas for smart clothing, ultra-robust miniature implantable UHF antennas, first mm-wave reverberation chamber equipped with multi-physics dosimetry instrumentation.

Research related to electromagnetic compatibility (EMC) is mainly focused on development of advanced measurements techniques and innovative modeling strategies for analysis of complex systems (cars, aircrafts, etc.). In particular, one of the mainstream research directions deals with advanced statistical analysis and development of engineering methods for reverberation chambers, including measurement of the antenna efficiency, radiation pattern, shielding efficiency, and radar cross-section. The team is also a major contributor to quantification of uncertainty propagation in EMC models through pioneering techniques such as controlled stratification.

WAVES team developed several unique experimental tools for BEM and EMC integrated into experimental platforms of the IETR (multi-physics dosimetry, reverberation chambers, GTEM cells, and near-field measurements)
