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 […] >>

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 […] >>

The most innovative communication systems for beyond 5G and future 6G applications have to face a number of challenges related to the trade-offs between link range, power consumption and data-rate. A growing interest is put on radio frequency circuits operating at mmW and sub-THz bands because at those frequencies there are large portions of available […] >>

Since 2018 and the announcement of the Spectre and Meltdow vulnerabilities, the hard-won performance gains of desktop and server processors over the past few decades have been called into question. These vulnerabilities effectively exploit the speculative and out of order execution found in all modern processors to gain in the number of instructions performed per […] >>

CESTI is an Information Technology Security Evaluation Facility (ITSEF) laboratory dedicated to security evaluations of integrated circuits. During its evaluation process, various tests can be performed, amongst whose perturbation attacks. The latter consists in modifying chip behavior in order to get secret keys, to bypass authentication steps or to get rid of specific countermeasures. Laser, […] >>
