OpenRIS: Democratizing reconfigurable intelligent surfaces for real-world wireless enhancements
Weicong Chen, Junjie Ai, Lin Bai +7
Wireless enhancement is critical for next-generation mobile communication systems to realize seamless connectivity, yet traditional network expansion strategies are becoming econom…
Angle-Dependent Phase Shifter Model for Reconfigurable Intelligent Surfaces: Does the Angle-Reciprocity Hold?
Weicong Chen, Lin Bai, Wankai Tang +3
The existing phase shifter models adopted for reconfigurable intelligent surfaces (RISs) have ignored the electromagnetic (EM) waves propagation behavior, thus cannot reveal practi…
A novel EM concentrator with open-concentrator region based on multi-folded transformation optics
Hamza Ahmad Madni, Khurram Hussain, Wei Xiang Jiang +5
Conventional concentrators with inhomogeneous coating materials that fully enclose the destined region pose great challenges for fabrication. In this paper, we propose to design an…
Leaky-Wave Radiations by Modulating Surface Impedance on Subwavelength Corrugated Metal Structures
Ben Geng Cai, Yun Bo Li, Hui Feng Ma +3
One-dimensional (1D) subwavelength corrugated metal structures has been described to support spoof surface plasmon polaritons (SPPs). Here we demonstrate that a modulated 1D subwav…
Polarization-controlled anisotropic coding metamaterials at terahertz frequencies
Shuo Liu, Tie Jun Cui, Quan Xu +12
Metamaterials based on effective media have achieved a lot of unusual physics (e.g. negative refraction and invisibility cloaking) owing to their abilities to tailor the effective…
Creation of Ghost Illusions Using Metamaterials in Wave Dynamics
Weixiang Jiang, Cheng-Wei Qiu, Tiancheng Han +2
The creation of wave-dynamic illusion functionality is of great interests to various scientific communities, which can potentially transform an actual perception into the pre-contr…
