Towards Outdoor Electromagnetic Field Exposure Mapping Generation Using Conditional GANs

Mohammed Mallik, Angesom Ataklity Tesfay, Benjamin Allaert, Rédha Kassi, Esteban Egea-Lopez, Jose-Maria Molina-Garcia-Pardo, Joe Wiart, Davy Gaillot, Laurent Clavier

With the ongoing fifth-generation cellular network (5G) deployment, electromagnetic field exposure has become a critical concern. However, measurements are scarce, and accurate electromagnetic field reconstruction in a geographic region remains challenging. This work proposes a conditional…

Unstationary dynamics of drops subjected to MHz-surface acoustic waves modulated at low frequency

Philippe Brunet, Michael Baudoin

In the present work, we investigate the unstationary dynamics of sessile droplets subjected to high-frequency surface acoustic waves modulated at a lower frequency close to the first inertio-capillary resonance mode of the drop. Under the action of both acoustic streaming and radiation pressure,…

High Breakdown Field and Low Trapping Effects up to 1400 V in Normally Off GaN‐on‐Silicon Heterostructures

Idriss Abid, Youssef Hamdaoui, Jash Mehta, F Medjdoub

In this study, we report on the development of a fully normally-off high electron mobility transistor (HEMT) gallium nitride on silicon (GaN-on-Si) heterostructures designed for high voltage operation. The normally-off configuration was achieved by means of a p-gallium nitride (p-GaN) cap layer…

Exceptional Points and Skin Modes in Non-Hermitian Metabeams

Runcheng Cai, Yabin Jin, Yong Li, Timon Rabczuk, Yan Pennec, Bahram Djafari-Rouhani, Xiaoying Zhuang

We present a non-Hermitian metabeam exhibiting an exceptional point (EP) induced by enforcing parity-time (PT) symmetry through applied external forces. The EP is formed by the hybridization of two flexural wave modes and its output displacement is enhanced by attaching two pillars on top of the…

High speed, antenna-enhanced 10.3 μm quantum cascade detector

G. Quinchard, C. Mismer, M. Hakl, J. Pereira, Quyang Lin, Sylvie Lepilliet, V. Trinité, A. Evirgen, Emilien Peytavit, J. Reverchon, Jean-Francois Lampin, S Barbieri, A. Delga

The strong potential of intersubband detectors in the field of mid-infrared photodetection places this technology as a relevant alternative to HgCdTe detectors in the race for ultrafast operation. While their extremely short photocarrier's lifetime opens up possibilities of detection beyond…

Compact Multi-Band Flexible Antenna for ISM, WLAN, Wi-Fi, and 5G sub-6-GHz Applications

Syed Muhammad Rizvi Jarchavi, Mohsin Iqbal, Mariana Dalarsson, Mohammad Alibakhshikenari, Iyad Dayoub

Design and analysis of a compact multi-band flexible antenna are presented here. The antenna is designed using the flexible substrate material Rogers 5880 and has a compact size of 18mm×18mm×0.254mm. The coplanar waveguide (CPW) fed radiator consists of a rectangular-shaped patch modified using a…

Facile and secure synthesis of porous partially fluorinated graphene employing weakly coordinating anion for enhanced high-performance symmetric supercapacitor

Ning Cao, Teng Wang, Rabah Boukherroub, Yinghui Cai, Yijiang Qin, Fashun Li, Peng Liu, Qingguo Shao, Mingle Liu, Xiaobei Zang

In this paper, porous partially fluorinated graphene (PFG) for supercapacitors (SCs) was fabricated by a mild and secure one-pot hydrothermal method utilizing weakly coordinating anion BF4− as the fluorine source. The hydrolysis rate of sodium fluoroborate was adjusted by controlling the reaction…

Bragg's additivity rule and core and bond model studied by real-time TDDFT electronic stopping simulations: The case of water vapor

Bin Gu, Daniel Muñoz-Santiburcio, Fabiana da Pieve, Emilio Artacho, Jorge Kohanoff, Fabrizio Cleri

The electronic stopping power (Se) of water vapor (H2O), hydrogen (H2) and oxygen (O2) gases for protons in a broad range of energies, centered in the Bragg peak, was calculated using real-time time-dependent density functional theory (rt-TDDFT) simulations with Gaussian basis sets. This was done…
