Power grid is the heart of recent concerns due to climate, economic and geostrategic risks. If the safety and performance of these systems are essential subjects to study, the resilience of energy systems to cyber-attacks is an issue that cannot be ignored. Indeed, energy systems are now the target of computer attacks carried out by […] >>

Reconfigurable Intelligent Surfaces (RISs), which consist of nearly-passive controllable devices (behaving as e.g., electromagnetic mirrors, lenses, or large sensing surfaces), have already shown promising potential to boost -or even sometimes just to enable- data communication and localization capabilities in next-generation wireless networks, while limiting the need of active base stations. Conversely, RISs could also be […] >>

Wireless power transmission technologies (WPT) are rapidly expanding, particularly for wireless charging of electrical systems (mobile phones, electric cars, etc.) but also for powering centimeter-scale wireless sensor nodes. The aim of the thesis is to study the performance and optimization of a new electrodynamic system concept recently proposed in our laboratory. The operation of this […] >>

Silicon/Germanium spin qubits have made outstanding progress in the past two years [Nature 591, 580 (2021); arXiv:2202.09252]. In these devices, the elementary information is stored as a coherent superposition of the spin states of an electron in a Si/SiGe heterostructure, or of a hole in a Ge/SiGe heterostructure. These spins can be manipulated electrically owing […] >>

As part of the development of its research activities on sensor networks and predictive maintenance, the Autonomy and Sensor Integration Laboratory (DSYS/SSCE/LAIC) of CEA-LETI in Grenoble, France, is offering a thesis on “Ultrasound-based predictive maintenance”. Ultrasound emission is one of the first signs of ageing in an industrial system, before the appearance of vibrations, noise […] >>
