Chalcogenide nano-optomechanical phase change metasurface

Ding Li, Abbas Sheikh Ansari, Avik Mandal, Behrad Gholipour, Xin Zhou, Jun-Yu Ou

Tuning any mechanical resonator like a guitar string requires continuous force and energy. Phase change chalcogenide semiconductors can provide non-volatile switching of mechanical and optical properties with phase transition. Here, we demonstrate a new class of reconfigurable nano-optomechanical…

Noise sources, data process and uncertainties in terahertz time domain spectroscopy

Jeyan Bichon, Noureddin Osseiran, Jean-Francois Lampin, Romain Peretti

The first terahertz time domain spectroscopy (THz-TDS) experiments are now well-established, and fully autonomous systems have been commercially available for over a decade. This has led to the increasing adoption of THz-TDS by research groups outside the core THz community, as well as by…

Thermoelastic properties of polycrystalline strontium titanium silicate Sr₂TiSi₂O₈ synthesized via the reactive sintering method

Oussama Zwein, Maurice Gonon, Sandra Abdelouhab, Isabella Mastroianni, Marc Duquennoy

The aim of the work presented in this paper is to investigate the thermoelastic properties of polycrystalline Sr-fresnoite Sr2TiSi2O8 (STS). On that purpose, Sr2TiSi2O8 samples were synthesized by solid state reactive sintering from SrCO3, TiO2 and SiO2 powders. The thermal expansion behaviour of…

Light security scheme for Cooperative, Connected and Automated Mobility (CCAM)

Ramzi Boutahala, Hacène Fouchal, Marwane Ayaida

Cooperative, Connected and Automated Mobility (CCAM) is a new paradigm adopted by academia and industry in order to provide safe, secure and sustainable mobility on all kinds of roads (highways, urban and rural roads). CCAM takes advantage of Cooperative Intelligent Transport Systems (C-ITS) to…

Infrastructure intelligente pour l'allocation de puissance dans les systèmes MIMO de type cell-free

Philippe Mathieu, Antoine Nongaillard, Eric Pierre Simon

Les réseaux de télécommunication actuels, basés sur des stations centralisées, ne répondent pas aux besoins croissants en bande passante et aux nouveaux usages comme l'IoT ou les véhicules connectés. Le paradigme "cell-free" émerge comme une solution, distribuant des points d'…, Current telecommunication networks, based on centralized base stations, do not meet the growing demand for bandwidth and new uses such as IoT or connected vehicles. The "cell-free" paradigm emerges as a solution, distributing less powerful but more numerous access points over a wide area…

Physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers for power electronics applications

Ndembi Ignoumba-Ignoumba, Camille Sonneville, Adrien Bidaud, Pierre Brosselard, Eric Frayssinet, Florian Bartoli, Yvon Cordier, Farid Medjdoub, Dominique Planson, Cyril Buttay

This work presents physical and electrical characterizations of low n-doped MOCVD GaN-on-sapphire layers and associated quasi-vertical Schottky Barrier Diodes (SBDs). Samples GaN drift layers have globally a similar quality as examined by XRD, AFM Raman spectroscopy, C-V measurements and I-V…

Patterning and micromanipulation of miscible fluids using vortex-based single-beam acoustic tweezers

Samir Almohamad, Gustav Modler, Ravinder Chutani, Udita Ghosh, Sarah Cleve, Henrik Bruus, Michael Baudoin

Vortex-based single-beam tweezers have the ability to precisely and selectively move a wide range of objects, including particles, bubbles, droplets, and cells with sizes ranging from the millimeter to micrometer scale. In 2017, Karlsen and Bruus [Phys. Rev. Appl. 7, 034017 (2017)] theoretically…
