Topological Berry Antenna on a Silicon Chip for Terahertz Wireless Communication

Sonu Kumar, Ridong Jia, Yi Ji Tan, Thomas Caiwei Tan, Pascal Szriftgiser, G Arun Kumar, Guillaume Ducournau, Arokiaswami Alphones, Ranjan Singh

Nonzero Berry curvature is central to the existence of topological edge states in electronic and photonic valley-Hall systems. While manipulating the Berry curvature in condensed matter systems is challenging, valley-Hall topological photonics offer unprecedented control, where the broken spatial…

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…

Drying Behavior of Flax Stems at Different Degrees of Dew Retting Under Simulated Rainfall: Implications for Smart Agriculture and Sensor Development

Ali Reda, Lionel Buchaillot, Steve Arscott

Dew retting of flax stems is a key agricultural process which facilitates fiber extraction from parent stems. If sensors are to be developed to monitor the degree of retting for optimal fiber extraction, then stem characteristics such as water uptake and loss need to be accurately known. Here, the…

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…

Recueil de communications école d'hiver 2025 GDR ARCHI-META - DN METACMED

Marco Miniaci, Giuseppe Rosi, Nicolas Auffray, Cédric Bellis, Christelle Combescure, Justin Dirrenberger, Kerem Ege, Muamer Kadic, Fabrice Lemoult, Bruno Morvan, Vincent Pagneux, Julien Poittevin, Martin Poncelet

The last 20 years have seen a remarkable growth in scientific interest in (elastic and mechanical) metamaterials. One of the reasons for this is the great potential that this subject area has in itself as a “link between different disciplines”, particularly acoustics and solid mechanics. In…

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…

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…
