Optical properties of HgTe nanocrystals

Guy Allan, Christophe Delerue, Ali Al-Otaify, David J. Binks, Stephen V. Kershaw, Shuchi Gupta, Andrey L. Rogach

HgTe nanocrystals presently receive growing interest because the negative band gap in bulk HgTe enables tunability of the gap from the infrared to the near infrared in quantum dots thanks to the quantum confinement. Therefore we propose a tight-binding model of HgTe which gives an accurate band...

Energy transfer between acoustic fields by dry frictional contacts for SHM: a lumped numerical analysis

Konstantinos Gryllias, Eric Chatelet, Francesco Massi, Emmanuel Moulin

This paper investigates the concept of transferring / pumping vibroacoustic energy from an ambient acoustic field towards a secondary acoustic field by exploiting the dry contact friction nonlinearities. The secondary acoustic field could be used, for instance, as a reference signal in structural...

Cascaded Brillouin fibre lasers coupled to unitravelling carrier photodiodes for narrow linewidth terahertz generation

Guillaume Ducournau, Denis Bacquet, P. Szriftgiser, Fabio Pavanello, Emilien Peytavit, Mohamed Zaknoune, Alexandre Beck, Jean-Francois Lampin

Narrow linewidth terahertz (THz) generation using a cascaded Brillouin fibre laser structure and a unitravelling carrier photodiode is investigated. Using two distributed feedback lasers separated by > 1 THz with 1 MHz initial linewidth, the use of the cascaded Brillouin laser greatly increases...

Design and radiation hardness of next generation solar UV radiometers

Samuel Gissot, Ali Benmoussa, Boris Giordanengo, Ali Soltani, Terubumi Saito, Udo Schühle, Udo Kroth, Alexander Gottwald

For next space-based ultraviolet (UV) solar radiometers, we propose a design based on subsystem components that are selected according to lessons learned from previous flying missions and ground irradiation campaigns. UV interference filters inherited from space-based solar missions show strong...

Métasurface absorbante parfaite à base de cubes ferroélectriques distribués aléatoirement

Véronique Sadaune, Ludovic Burgnies, Eric Lheurette, Jianping Hao, Didier Lippens

L'utilisation d'une structure périodique de cubes de BaSrTiO3 interfacée avec une surface métallique par un fin film diélectrique permet d'obtenir une absorption proche de 100% à la fréquence de résonance de Mie magnétique. Cette absorption reste élevée pour un angle d'incidence...

Caractérisation diélectrique des matériaux de construction dans le domaine des hyperfréquences

M.D. Belrhiti, S. Bri, A. Nakheli, Ahmed Mamouni

Dans la littérature, une variété de techniques pour extraire les paramètres constitutifs est disponible. Ces techniques incluant les méthodes résonantes et non résonantes avec leurs avantages et inconvénients sont également discutées. La caractérisation des matériaux de construction à l'aide...

Features of acoustic resonance in iron borate

K.M. Skibinsky, M.B. Strugatsky, S.V. Yagypov, A.I. Yevstafyev, V.L. Preobrazensky, V.N. Bersansky

Acoustic resonance in a weak-ferromagnetic iron borate monocrystal was investigated. It was shown that observed field dependence of positions and magnitudes of the resonance peaks can be explained within framework of the developed theory of magnetic birefringence of sound in the inhomogeneous...

CW Radar for Monitoring Water-to-Cellular Concrete

Kamel Haddadi, Tuami Lasri

The physical deterioration of concrete structures is mainly caused by their moisture content. Consequently, methods dedicated to contactless, non-destructive and real-time monitoring of moisture content levels are required to control the deterioration of buildings. In this study, we propose an...

Direct path detection algorithm in multiple input single output configuration for transport applications

Kobenan Ignace Kossonou, Yassin El Hillali, Michael Bocquet, Atika Rivenq, Jamal Assaad

This paper introduces a novel technique that exploits cross-correlation properties of near-orthogonal pseudonoise (PN) codes to estimate the time of arrival of the direct path signal for Multiple Input Single Output (MISO) applications. Indeed, multipath are a source of error in the time...

Simulation of the metal-semiconductor-metal photodetector based on InGaAs for the photodetection at the wavelength 1.55 µm

M. El Besseghi, Abdelkader Aissat, Didier Decoster

In this paper we present the simulation of Metal-Semiconductor-Metal photodetector (MSM-PD) of interdigitated planar structure based on InAlAs/InGaAs adapted for photodetection at the wavelength 1.55 μm. We use the theoretical models to plot the variations of the dark current, the photocurrent, the...
