The identification of bacterial species is an important issue in the context of health risk assessment, but is often insufficient. but often insufficient. Indeed, the presence of VNC (Viable Non-Cultivable) bacteria poses a problem because they cannot be detected by classical microbiological techniques, which are based on techniques, which are based on the culture of […] >>

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 […] >>

Spatiotemporal manipulation of the near- and far-electromagnetic (EM)-field distribution and its interaction with matter in the THz spectrum (0.1-0.6 THz) is of prime importance in the development of future communication, spectroscopy, imaging, holography, and sensing systems. Reconfigurable Intelligent (Meta)Surface (RIS) is a cutting-edge hybrid analogue/digital architecture capable of shaping and controlling the THz waves at […] >>

Emission imaging is a medical imaging modality using radiopharmaceuticals, enabling to retrieve functional information. It is highly specific and sensitive to very small concentrations of the tracer. However, current instruments like scintillation cameras measure only a small fraction of emitted photons. Positrons cameras are more sensitive but limited to beta+ emitters. Recent improvements in the […] >>

The thesis concerns the study, modeling and development of infrared detectors based on antennas and MIM (Metal-Insulator-Metal) nanodiodes in the range 8-12 µm. These devices will operate at room temperature and will be manufactured in the CEA-LETI clean room. The student began his thesis work with a theoretical study of the behavior of dielectric and […] >>
