Offer Description

Metamaterials are artificial structures that exhibit properties not found in natural materials [1]. The engineering of metamaterials has had a significant impact on physics, specifically in the control of electromagnetic (EM) waves (microwaves, terahertz, and optics). The advent of these materials offers new possibilities for realizing physical phenomena such as negative refractive index [2] or invisibility cloaking [3]. These materials hold great promises for the development of new applications.

A metasurface is a two-dimensional version of a metamaterial, with a thickness that is significantly smaller than the wavelength [4-8] and consists of a periodic array of subwavelength cells. A metasurface can be directly printed using standard printed circuit board (PCB) technology on a rigid dielectric or flexible organic substrate, allowing it to conform to non-planar structures. Additionally, its ultra-thin thickness greatly reduces undesirable dielectric losses in transmission. Metasurfaces exhibit unique properties in transmission and reflection, where both amplitude and phase can be efficiently controlled.

The Electromagnetism & Signal department at the Energetics Mechanics Electromagnetics Laboratory (LEME) focuses on the study and engineering of the properties of metasurfaces. Specifically, the LEME’s activities include both theoretical and experimental investigations of metasurfaces for applications related to radiofrequency antennas, sensors, and microwave devices. By integrating lumped electronic components, different functionalities can be tailored from a single metasurface [9].

However, while these structures are reconfigurable and highly efficient, they require external user intervention to modify and control the functionality of the structure. In contrast, this doctoral thesis proposal aims to evolve towards fully autonomous and intelligent systems capable of sensing and capturing the external environment state and self-adapting for the desired application [10]. The main objective of this thesis is to combine expertise in reconfigurable metasurface design with embedded electronics to develop autonomous and intelligent metasurfaces that self-adapt dynamically to incoming waves (especially in dynamic environments) for stealth.
