Exploring Symmetry in Wireless Propagation Channels [PDF]

arXiv, 2017
Wireless communications literature is very rich with empirical studies and measurement campaigns that study the nature of the wireless propagation channel. However, despite their undoubted usefulness, many of these studies have omitted a fundamental yet key feature of the physical signal propagation, that is, wireless propagation asymmetry.

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

Advanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Single‐Step Fabrication of a 3D Stretchable Inductor with Multi‐jet Modeling Printing Technology

Advanced Materials Technologies, EarlyView.
This paper presents a single‐step process using multi‐jet modeling 3D printing to fabricate hybrid polymeric matrices for stretchable 3D inductors. The technology of printing both rigid and stretchable materials in a single process reduces the fabrication steps, while the novel design of the access channels ensures uniform coil channel dimensions ...

Surveillance and Intervention of Infrastructure-Free Mobile Communications: A New Wireless Security Paradigm [PDF]

arXiv, 2016
Conventional wireless security assumes wireless communications are rightful and aims to protect them against malicious eavesdropping and jamming attacks. However, emerging infrastructure-free mobile communication networks are likely to be illegally used (e.g., by criminals or terrorists) but difficult to be monitored, thus imposing new challenges on ...
