Rotating ULA-Enabled Computed Tomography for Efficient 3D Spatial Power Spectrum Synthesis: Architecture and Principled Orientation Design
Haocheng Hua, Weidong Mei, Jie Xu +1
This paper proposes an efficient three-dimensional (3D) spatial power spectrum synthesis method by rotating a uniform linear array (ULA) about its center in 3D space. Inspired by c…
Bending Beam for THz Wireless Networks: Fundamental, Design Issue, and Prototype
Aoran Liu, Xin Tong Hu, Weidong Mei +5
Bending beams, characterized by their non diffracting and self-healing properties in the near field, offer a new approach to bypass blockage in terahertz (THz) wireless communicati…
Frequency-switching Array Enhanced Physical-Layer Security in Terahertz Bands: A Movable Antenna Perspective
Cong Zhou, Changsheng You, Chao Zhou +4
In this paper, we propose a new frequency-switching array (FSA) to enhance the physical-layer security (PLS) in the presence of multiple eavesdroppers (Eves), where the carrier fre…
Minimizing Movement Delay for Movable Antennas via Trajectory Optimization
Qingliang Li, Weidong Mei, Boyu Ning +1
Movable antennas (MAs) have received increasing attention in wireless communications due to their capability of antenna position adjustment to reconfigure wireless channels. Howeve…
