Reconfigurable Intelligent Surfaces based RF Sensing: Design, Optimization, and Implementation
Jingzhi Hu, Hongliang Zhang, Boya Di +5
Using radio-frequency (RF) sensing techniques for human posture recognition has attracted growing interest due to its advantages of pervasiveness, contact-free observation, and pri…
Intelligent Electromagnetic Sensing with Learnable Data Acquisition and Processing
Hao-Yang Li, Han-Ting Zhao, Meng-Lin Wei +4
Electromagnetic (EM) sensing is a wide-spread contactless examination technique in science, engineering and military. However, conventional sensing systems are mostly lack of intel…
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…
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…
Through-the-Wall Imaging Exploiting 2.4GHz Commodity Wi-Fi
Wei Zhong, Kai He, Lianlin Li
In this letter, we experimentally investigate a low-cost through-the-wall imaging exploiting Wi-Fi signals in an indoor environment from the perspective of holographic imaging. In…
Performance Analysis and Dynamic Evolution of Deep Convolutional Neural Network for Nonlinear Inverse Scattering
Lianlin Li, Long Gang Wang, Fernando L. Teixeira
The solution of nonlinear electromagnetic (EM) inverse scattering problems is typically hindered by several challenges such as ill-posedness, strong nonlinearity, and high computat…
