Ultra-thin normal-shear-coupled meta-barrier for low-frequency underwater sound insulation

Marco Miniaci, Vinicius Fonseca Dal Poggetto

Underwater noise pollution from anthropogenic activities, such as offshore oil and gas exploration, poses significant threats to marine life. A common mitigation strategy involves enclosing primary noise sources within physical barriers to reduce noise levels in surrounding environments. Underwater…

Nonlinear modeling of AlN/GaN HEMT accounting for self-biasing effect during RF step stress: analysis and hard-SOA

Nasri Said, Damien Saugnon, K. Harrouche, F Medjdoub, N. Labat, N. Malbert, Jean-Guy Tartarin

In this study, we investigate the non-linear (NL) behavior of AlN/GaN HEMT technologies under gain compression when submitted to 10 GHz single-tone RF-step stress, which is crucial for millimetre-wave power application robustness. We evaluate AlN/GaN transistors, targeting high-power amplifiers…

Toward Smart Probes for mmW On-Wafer Measurements: Advanced Packaging Using Laser Micromachining of Glass

Maya Alawar, Victor Fiorese, Sylvie Lépilliet, Daniel Gloria, Guillaume Ducournau, Emmanuel Dubois

This article introduces the development of groundsignal-ground (GSG) probes for on-wafer active measurements, fabricated using femtosecond laser micromachining with a resolution between 5 and 10 µm. The probes are made from a 100 µm-thick Schott AF32 glass substrate bonded to a 10 µm-thick nickel…

Leveraging 3GPP Features and Optimization Techniques for 5G NR-V2X Resource Allocation: A Survey

Chaeriah Bin Ali Wael, El Hadj Dogheche, Nasrullah Armi, Agus Subekti, Iyad Dayoub

Cellular Vehicle-to-everything (C-V2X) communication is critical for Intelligent Transportation Systems (ITS), facilitating information exchange among road users and infrastructure. Since its first introduction in rel-15 by 3GPP, 5G NR-V2X features have continued to evolve, aiming to support…

Brain‐Inspired Polymer Dendrite Networks for Morphology‐Dependent Computing Hardware

Corentin Scholaert, Yannick Coffinier, Sébastien Pecqueur, Fabien Alibart

Process variation is always a challenge to mitigate in electronics. This especially holds true for organic semiconductors, where reproducibility concerns hinder industrialization. Challenging this concept, it shows AC-electropolymerization to be a powerful platform for the development of morphology…

A Universal Implementation Approach for Multivalued Logic Gates Based on Negative Transconductance in Series-Connected Two-Dimensional Transistors

Guangchao Zhao, Wanting Wen, Keyi Liao, Philippe Coquet, Xingli Wang, Mingqiang Huang, Beng Kang Tay

Multiple-valued logic (MVL) is highly desired for algebra, logic, and artificial intelligence due to its higher information density. However, its practical adoption has been hindered for decades by extensive hardware requirements. Two-dimensional (2D) materials with exceptional electronic…
