"This project will study the control of electromagnetic (EM) waves using exceptional materials, and the application of such to the design of novel adaptive guiding and radiating structures. Two classes of unusual ‘materials’ with similarities in terms of modelling method and potentials applications are concerned here, constituting two inter-related research lines (i) the nano-scale graphene material and (ii) artificial materials based on periodic structures.
Concerning graphene, a first goal will be to derive simple yet efficient EM models for the monolayer atomic structure, derived from usual EM concepts and solid-state properties of graphene. Such modelling will be experimentally validated and then employed to the design of graphene-based devices, including wired and wireless intrachip interconnects and antennas. A very important aspect in this task is the tremendous potential of graphene for fully-integrated and effective device dynamic control, based on field-effect.
In the case of artificial material made of periodic structures, they will be combined with MicroElectroMechanical Systems (MEMS) in order to achieve integrated EM devices with dynamic control capabilities. At the theoretical level, the properties of the periodic structures will be tailored to achieve unprecedented radiation capabilities (e.g. the total control of the radiated beam at all space directions).
The frequency range of interest for these studies mainly concern millimeter-waves, but THz will also be considered in particular cases. Very importantly, both theoretical and experimental aspects will be carefully addressed. This ambition requires exceptional expertise and fabrication capabilities, which is available within the applicant team and host infrastructure and multidisciplinary activities. This research will significantly contribute to the crucial fields of nano-electromagnetics devices, dynamic configuration, and fully-tailored electromagnetic radiation for advanced applications."
