Rayleigh Waves in Phononic Crystal Made of Multilayered Pillars: Confined Modes, Fano Resonances, and Acoustically Induced Transparency

M. Oudich, Bahram Djafari-Rouhani, B. Bonello, Yan Pennec, S. Hemaidia, F. Sarry, D. Beyssen

We present a design of phononic crystal based on pillars distributed on a substrate surface in which each pillar is constructed by a periodic stacking of PMMA and silicon layers. The pillar behaves like a one-dimensional phononic crystal which allows the creation of band gaps that prohibits wave…

The role of dispersion forces on the atomic structure of glassy chalcogenides: The case of GeSe4 and GeS4

Ziyad Chaker, Guido Ori, Christine Tugène, Sébastien Le Roux, Mauro Boero, Carlo Massobrio, Évelyne Martin, Assil Bouzid

Recent first-principles molecular dynamics simulations (FPMD) results on two chalcogenide glasses (glassy GeS4 and GeSe4) are revisited by accounting explicitly for van der Waals (vdW) dispersion forces. This effort is motivated by the observation that such contributions were found to be important…

Suppression of contact noise in a study on 1/ f noise as a function of film thickness in Al-doped ZnO

Abicha Achahour, Gérard Leroy, L.K.J. Vandamme, Boubakeur Ayachi, Benoît Duponchel, Nicolas Waldhoff, Karine Blary, Jean-Pierre Vilcot

Aluminum doped-zinc oxide (AZO) thin films were prepared on glass substrate by radio-frequency (RF) sputtering at room temperature. The sheet resistance, Rsh [Ω] the resistivity, ρ [Ω·cm] and the 1/f noise were studied as a function of thickness, t from 50 nm to 450 nm. The eddy current…

Chapter 5 - Transmission in 2D phononic crystals and acoustic metamaterials

Yan Pennec, Bahram Djafari-Rouhani, Abdellatif Akjouj, Gaëtan Lévêque, El Houssaine El Boudouti, Housni Al-Wahsh, L. Dobrzynski

In this chapter we describe the basic concepts of two-dimensional (2D) phononic crystals. We start with a detailed presentation of the elementary methods for the calculation of band structures and transmission phenomena which have proven their efficiency in the literature. We respectively present…

Propagation of elastic waves in a one-dimensional high aspect ratio nanoridge phononic crystal phononic crystal

Abdellatif Gueddida, Yan Pennec, El Houssaine El Boudouti, George Fytas, Bahram Djafari-Rouhani

We investigate the propagation of elastic waves in a one-dimensional (1D) phononic crystal constituted by high aspect ratio epoxy nanoridges that have been deposited at the surface of a glass substrate. With the help of the finite element method (FEM), we calculate the dispersion curves of the…

Effect of MoS2 layer on the LSPR in periodic nanostructures

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

Abstract In this work, we propose a new configuration of the localized surface plasmon resonance (LSPR), based on MoS2 hybrid structures for ultrasensitive biosensing applications. The plasmonic resonances are widely used in bimolecular detection and continue to be an active network because of the…

On the two-way diamond relay channel with lattice-based Compress-and-Forward

Anne Savard, Laurent Clavier

This paper focuses on the full-duplex Gaussian two-way diamond relay channel (TWDRC), where two users wish to exchange their messages with the help of two relays, when one relay performs a lattice-based Compress-and-Forward (CF) scheme. The other relay performs either Decode-and-Forward (DF),…

A broadband 4-18 GHz active quadrature hybrid

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of a broadband active quadrature hybrid. This novel architecture consists of a traveling wave amplifier with a unique coupling mechanism, providing amplitude flatness and low phase imbalance over the 4 - 18 GHz frequency band. Experimental results validate…
