Polymer photonic crystal membrane for thermo-regulating textile

Salim Assaf, Mohamed Boutghatin, Yan Pennec, V. Thomy, Alexander Korovin, A. Treizebre, Michèle Carette, Abdellatif Akjouj, Bahram Djafari-Rouhani

We study numerically the absorption and scattering properties of a polymer photonic membrane to thermoregulate the human body microclimate which corresponds to the area between the skin and a textile. We first show that the structuration of the absorbing photonic membrane with air holes leads to a...

Proposal for an integrated silicon-photonics terahertz gas detector using photoacoustics

Mattias Verstuyft, Elias Akiki, Benjamin Walter, Marc Faucher, Jean-Francois Lampin, Mathias Vanwolleghem, Bart Kuyken

A design and multiphysical model is presented for an on-chip gas sensor that transduces terahertz gas absorption through sound generation into a mechanical motion that can be read out externally. The signal is triply enhanced by designing a structure that functions simultaneously as an optical, an...

Reference-free damage localization based on pump-probe measurements

Marina Terzi, Lynda Chehami, Emmanuel Moulin, Nikolay Smagin, Vladislav Aleshin

Nondestructive testing is often based on comparison between experimental data measured on damaged and intact samples. However, properties of intact samples can change with time, temperature or other external factors. An alternative approach discussed here solely uses data obtained on a damaged...

Nanomechanical modulation cavities of localized surface plasmon resonance with elastic whispering-gallery modes

Z. Oumekloul, M. Moutaouekkil, Gaëtan Lévêque, Abdelkrim Talbi, A. Mir, Abdellatif Akjouj

he dispersion of mechanical vibration limits nano-optomechanical modulation. In this work, we propose an optomechanical modulation exploiting elastic local resonances, also called whispering-gallery modes (WGMs). We find that our structure supports two quadripolar and two hexapolar elastic WGMs,...

Surface Functionalization with Polyethylene Glycol and Polyethyleneimine Improves the Performance of Graphene-Based Materials for Safe and Efficient Intracellular Delivery by Laser-Induced Photoporation

Jing Liu, Chengnan Li, Toon Brans, Aranit Harizaj, Shana van de Steene, Thomas de Beer, Stefaan de Smedt, Sabine Szunerits, Rabah Boukherroub, Ranhua Xiong, Kevin Braeckmans

Nanoparticle mediated laser-induced photoporation is a physical cell membrane disruption approach to directly deliver extrinsic molecules into living cells, which is particularly promising in applications for both adherent and suspension cells. In this work, we explored surface modifications of...

Physicochemical characterizati on of the fuel by the ultrasound method

Said Soudani, Mohammed Mekkaoui, Georges Nassar, Ziane Derouiche

A physical medium, whatever its nature ,solid, liquid or gaseous is characterized by physicochemical parameter which are unique to it and which differentiate it from any other medium. But it can also be characterized and differentiated by its acoustic parameters: it’s like two sides of the same...

L'infini au cours des siècles

Stefano Giordano, Manon Benedito

The fascinating history of the concept of infinity is indissolubly associated with the development of religions, philosophies, mathematics and natural sciences. At the time of the first Greek philosophers, the infinity, or áperion, was a negative concept to be avoided in all rigorous statements....

Active control of the transmission of Lamb waves through an elastic metamaterial

W. Wang, B. Bonello, Bahram Djafari-Rouhani, X. Fang, Yan Pennec, J. Zhao, Y. Jin

We have numerically investigated the transmission of an antisymmetric Lamb wave through a line of silicon pillars erected onto a homogeneous silicon plate when the frequency is tuned to a resonant frequency of the pillars. For either a bending mode or a compressional mode, the resonators emit in...

Channel Estimation Techniques for Millimeter-Wave Communication Systems: Achievements and Challenges

Kais Hassan, Mohammad Masarra, Marie Zwingelstein, Iyad Dayoub

The fifth-generation (5G) of cellular networks and beyond requires massive connectivity, high data rates, and low latency. Millimeter-wave (mmWave) communications is a key 5G enabling technology to meet these requirements thanks to its technical potentials that can be integrated with other 5G...
