Intelligent Meta-Imagers: From Compressed to Learned Sensing
Chloé Saigre-Tardif, Rashid Faqiri, Hanting Zhao +2
Computational meta-imagers synergize metamaterial hardware with advanced signal processing approaches such as compressed sensing. Recent advances in artificial intelligence (AI) ar…
Controllable Enhancements of Wi-Fi Signals at Desired Locations Without Extra Energy Using Programmable Metasurface
Ya Shuang, Hanting Zhao, Menglin Wei +2
We present for the first time an experimental demonstration on the energy allocation of commodity Wi-Fi signals in a programmable and inexpensive way. To that end, we design an ele…
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.…
Metasurface-Assisted Passive Wireless Communication with Commodity Wi-Fi Signals
Hanting Zhao, Ya Shuang, Menglin Wei +3
Wireless communication has become a standard solution to address ever-increasing demands for information transfer in our modern society. Conventional systems work in an active way…
Intelligent Metasurface Imager and Recognizer
Lianlin Li, Ya Shuang, Qian Ma +7
It is ever-increasingly demanded to remotely monitor people in daily life using radio-frequency probing signals. However, conventional systems can hardly be deployed in real-world…
