Analysis of Millimeter-Wave Polarization Diverse MIMO Capacity

, 2014
Millimeter-waves offer the possibility of wide bandwidth and consequently high data rate for wireless communications. For both uni- and dual-polarized systems, signals sent over a link may suffer severe degradation due to antenna misalignment.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Millimeter Waves, Millisecond Delays [PDF]

Proceedings of the 2nd ACM Workshop on Millimeter Wave Networks and Sensing Systems, 2018
Two simultaneous revolutionary changes are occurring in networking: the advent of mmWave networks and the advent of applications that require end-to-end delays of the order of a few milliseconds. mmWave is the first physical layer technology that promises huge wireless bandwidth, but with very poor reliability as a result of its vulnerability to ...

Vibration and Rotation in Millimeter-Wave SAR [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2007
Synthetic aperture radar (SAR) provides high-resolution images of static ground scenes, whereas processing of data containing ground object motion results in varying focusing effects. Special cases of such motion are vibration and rotation, which are closely related to each other.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
