Broadband super-resolution Terahertz Time domain spectroscopy applied to Gas analysis

Sophie Eliet, Arnaud Cuisset, Francis Hindle, Jean-Francois Lampin, Romain Peretti

Commercially available Terahertz (THz) Time domain spectroscopy (THz-TDS) apparatus are used in multiple application fields from material science to biology, and even in industry to measure the thickness of a paint layers. Its broad spectral coverage is of interest for air quality monitoring and…

Thermal interface : High thermal conductivity phase change materials for thermal management in high power electronic devices, Interface Thermique : Matériaux à changement de phase à haute conductivité thermique pour le management thermique des composants électroniques de puissance

Romain Hubert

Phase Change Material (P C M) have been widely used for thermal energy storage due to their highlatent heat of fusion for thermal management applications. However, P C M suffer from their verylow thermal conductivity which limits heat spreading around the heat source. Without properthermal…, Les matériaux à changement de phase (P C M) sont largement utilisés du fait de leur forte chaleur latente de fusion pour des applications de management thermique. Malgré cela, les P C M pâtissent de leur faible conductivité thermique qui limite la propagation de la chaleur autour de la source.Sans…

A perspective on elastic metastructures for energy harvesting

Zhihui Wen, Wan Wang, Abdelkrim Khelif, Bahram Djafari-Rouhani, Yabin Jin

Rapid advances have been made in the properties of metastructures, including phononic crystals, metamaterials, and metasurfaces, with respect to their robustness, high power density, and broadband behavior. This presents unique advantages for energy harvesting devices to meet the demands for…

Strong and weak polarization-dependent interactions in connected and disconnected plasmonic nanostructures

Damien Eschimèse, François Vaurette, Céline Ha, Steve Arscott, Thierry Mélin, Gaëtan Lévêque

We explore numerically and experimentally the formation of hybridized modes between a bright mode displayed by a gold nanodisc and either dark or bright modes of a nanorod – both elements being either separated by a nanometer-size gap (disconnected system) or relied on a metal junction (connected…

Stochastic Geometry-based Analysis of the Impact of Underlying Uncorrelated IoT Networks on LoRa Coverage

Romain Chevillon, Guillaume Andrieux, Laurent Clavier, Jean-François Diouris

IoT networks are more and more present nowadays. Some IoT protocols share the samebandwidth leading to interference on neighboring networks and decrease of overall coverage. To contributeto this problem, an analytical study of the coverage of a LoRa network with underlying uncoordinatedIoT networks…

On the Interference Arising From Random Spatial Fields of Interferers Utilizing Multiple Subcarriers

Ce Zheng, Malcolm Egan, Laurent Clavier, Gareth W. Peters, Jean-Marie Gorce

Efective symbol detection, channel estimation and decoding of channel codes require an accurate characterization of the noise probability distribution. In many systems, notably the internet of things, noise is largely in the form of interference, arising from a massive number of simultaneous…

Qualitative analysis of a 3D multiphysics model for nonlinear ultrasonics and vibration induced heating at closed defects

Kevin Truyaert, Vladislav Aleshin, Koen van den Abeele

Upon exciting a material using elastic waves, the locally induced deformation at the interfaces of internally closed defects may cause nonlinear wave mechanics and dynamics in the form of clapping and friction. As a result, both phenomena instigate spectral broadening of the excitation spectrum as…

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…
