Development of Smart Beamforming Architectures for 6G Telecommunication Systems
Over the past 20 years, wireless communication systems have continued to evolve and offer new services. Today, the success is such that the frequency bands below 10GHz are saturated and we are now turning to millimeter band frequencies. These frequencies offer the possibility to develop systems with higher data rates. However, they require beamforming to […] >>

Resonant antenna sensors for harsh environments
Microsystems sensors (MEMS) are the interface between the physical world and the digital world, and they are present today in most components and systems. A major challenge is the development of sensors that can be interrogated remotely, without electronic circuits or batteries, which will make it possible to envisage new applications as for example in […] >>

Assessment of Passive Radio Perturbations against Wireless Systems using Reconfigurable Surfaces
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 […] >>

Programmable electromagnetic (meta)surfaces at sub-THz frequencies
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 […] >>

mmW local oscillator signal generator with integrathed phase shifting capabilites
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 […] >>
