Metasurfaces Enable Active-Like Passive Radar
Mingyi Li, Jiawen Xu, Hanting Zhao +5
Passive radars (PRs) provide a low-cost and energy-efficient approach to object detection by reusing existing wireless transmissions instead of emitting dedicated probing signals.…
Optimal transmit field distribution for partially obstructed continuous radiating surfaces in near-field communication systems
Francesco Verde, Donatella Darsena, Marco Di Renzo +1
This paper deals with the optimal synthesis of aperture fields for (radiating) near-field communications in obstructed environments. A physically consistent model based on knife-ed…
Randomized Space-Time Stacked Intelligent Metasurfaces for Massive Multiuser Downlink Connectivity
Donatella Darsena, Ivan Iudice, Vincenzo Galdi +1
Stacked intelligent metasurfaces (SIMs) represent a key enabler for next-generation wireless networks, offering beamforming gains while significantly reducing radio-frequency chain…
Airy beams for radiative near-field communications: Fundamentals, potentials, and limitations
Donatella Darsena, Francesco Verde, Marco Di Renzo +1
In next-generation wireless networks, the combination of electrically large radiating apertures and high-frequency transmission extends the radiating near-field region around the t…
