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
Large-aperture reconfigurable intelligent surfaces (RISs) enable high-resolution 2D direction-of-arrival (DoA) estimation, but existing approaches still tie hardware cost and contr…
