CMT-Aware Channel Modeling and Transmit-Power Minimization for Pinching-Antenna Systems
Chuang Luo, Gui Zhou, Vasilis K. Papanikolaou +2
This letter investigates transmit-power minimization for multiuser pinching-antenna system (PAS) from a coupled-mode-theory (CMT)-aware perspective. Existing CMT-based pinching ant…
V-RIS: Virtual-Aperture DoA Estimation with Sparse RIS
Fenghao Zheng, Fuhai Wang, Zihan Jin +3
The paper introduces V-RIS, a method that uses only four corner subarrays of a reconfigurable intelligent surface and a single-antenna receiver to reconstruct a virtual‑aperture su…
Metasurface-Enabled Extremely Large-Scale Antenna Systems: Transceiver Architecture, Physical Modeling, and Channel Estimation
Zhengyu Wang, Tiebin Mi, Gui Zhou +1
Extremely large-scale antenna arrays (ELAAs) have emerged as a pivotal technology for addressing the unprecedented performance demands of next-generation wireless communication sys…
Source Localization and Power Estimation through RISs: Performance Analysis and Prototype Validations
Fuhai Wang, Tiebin Mi, Chun Wang +3
This paper investigates the capabilities and effectiveness of backward localization centered on reconfigurable intelligent surfaces (RISs). In the backward sensing paradigm, the re…
Swarm Antenna Arrays: From Deterministic to Stochastic Modeling
Tiebin Mi, Miyu Feng, Ruichu Shao +2
Swarm antenna arrays, composed of spatially distributed antennas mounted on unmanned agents, offer unprecedented flexibility and adaptability for wireless sensing and communication…
Toward Wireless Localization Using Multiple Reconfigurable Intelligent Surfaces
Fuhai Wang, Tiebin Mi, Chun Wang +3
