The activities of the group are devoted to the study and design of subwavelength structures for propagation control. They are based on the concept of metamaterial proposed at the beginning of the 21st century. The use of these artificial materials allows to extend the propagation properties (reflection, refraction, polarization, absorption, focusing...) in addition to the possibilities offered by conventional devices. These metamaterials are now available in the form of two-dimensional structures called metasurfaces.
These artificial materials are now used in many fields of wave physics with applications in the fields of optics, antennas, ElectroMagnetic Compatibility (EMC), acoustic insulation, seismic, etc.
The activities of our research group concern the physics of electromagnetic waves with a spectrum that extends from radiofrequencies to the infrared.
