Enhanced Information Security via Wave-Field Selectivity and Structured Wavefront Manipulation
Yufei Zhao, Deyu Lin, Qian Zhang +5
In this paper, we propose a novel secure wireless transmission architecture that enables the co-existence of spatial field modulation (SFM) and digital bandpass modulation (DBM), u…
Flexible Intelligent Layered Metasurfaces for Downlink Multi-user MISO Communications
Hong Niu, Jiancheng An, Chau Yuen
Stacked intelligent metasurfaces (SIMs) have recently gained attention as a paradigm for wave-domain signal processing with reduced reliance on costly radio-frequency (RF) chains.…
Introducing Meta-Fiber into Stacked Intelligent Metasurfaces for MIMO Communications: A Low-Complexity Design with only Two Layers
Hong Niu, Jiancheng An, Tuo Wu +8
Stacked intelligent metasurfaces (SIMs), which integrate multiple programmable metasurface layers, have recently emerged as a promising technology for advanced wave-domain signal p…
A Survey on Artificial Noise for Physical Layer Security: Opportunities, Technologies, Guidelines, Advances, and Trends
Hong Niu, Yue Xiao, Xia Lei +4
Due to the broadcast nature of wireless communications, physical-layer security has attracted increasing concerns from both academia and industry. Artificial noise (AN), as one of…
