Airy Beamforming for Radiative Near-Field MU-XL-MIMO: Overcoming Half-Space Blockage
Yifeng Qin, Jing Chen, Zhi Hao Jiang +3
The move to next-generation wireless communications with extremely large-scale antenna arrays (ELAAs) brings the communications into the radiative near-field (RNF) region, where di…
Non-Diffracting Beams for Near-Field Millimeter-Wave Communications: Advantage Regimes Under Aperture and Blockage Constraints
Yifeng Qin, Jing Chen, Zhi Hao Jiang +2
Near-field blockage changes the beam-design objective in millimeter-wave links: maximizing the unblocked on-axis gain does not necessarily maximize blocked-link performance. This p…
Negative reflection and negative refraction in biaxial van der Waals materials
Tan Zhang, Chunqi Zheng, Zhi Ning Chen +1
Negative reflection and negative refraction are exotic phenomena that can be achieved by platforms such as double-negative metamaterial, hyperbolic metamaterial, and phase-disconti…
Robust acoustic cloaking with density-near-zero materials
Jiajun Zhao, Tiancheng Han, Zhining Chen +2
Using the phenomenon of extraordinary sound transmission (EST) through artificially constructed density-near-zero (DNZ) materials, we propose an alternative approach to realize a v…
Acoustic Wavefront Manipulation: Impedance Inhomogeneity and Extraordinary Reflection
Jiajun Zhao, Cheng-Wei Qiu, Zhining Chen +1
Optical wavefront can be manipulated by interfering elementary beams with phase inhomogeneity. Therefore a surface allowing huge, abrupt and position-variant phase change would ena…
