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...

Trapped-mode-induced Fano resonance and acoustical transparency in a one-dimensional solid-fluid phononic crystal

Ilyasse Quotane, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate theoretically and numerically the possibility of existence of Fano and acoustic-induced transparency (AIT) resonances in a simple though realistic one-dimensional acoustic structuremade of solid-fluid layers inserted between two fluids. These resonances are obtained by combining...

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...

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),...

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...

Compact Waveguide and Guided Beam Pattern Based on the Whispering-Gallery Mode of a Hollow Pillar in a Phononic Crystal Plate

Weitao Yuan, Jinfeng Zhao, Bernard Bonello, Bahram Djafari-Rouhani, Xiaoqing Zhang, Yongdong Pan, Zheng Zhong

We report on the experimental evidence of the guiding of the lowest order antisymmetric Lamb mode (A0) through a compact waveguide consisting of aligned hollow pillars in between a square-latticed array of solid pillars on a thin slab. We analyze both numerically and experimentally the guiding...

Surface acoustic waves in one-dimensional piezoelectric-metallic phononic crystal: Effect of a cap layer

M. Alami, E. H. El Boudouti, Bahram Djafari-Rouhani, Y. El Hassouani, Abdelkrim Talbi

We study the propagation of transverse acoustic waves associated with the surface of a semi-infinite superlattice (SL) composed of piezoelectric-metallic layers and capped with a piezoelectric layer. We present closed-form expressions for localized surface waves, the so-called Bleustein-Gulyaev (BG...

Thin-film adhesion characterization by Colored Picosecond Acoustics

Arnaud Devos, P. Emery

This paper presents some applications of a recent technique so-called the Colored Picosecond Acoustics (APiC) to the characterization of complex stacks of thin films. The technique is a unique combination of optics and acoustics that implements an acoustic pulse-echo technique at the nanoscale...

Voltage controlled sub-THz detection with gated planar asymmetric nanochannels

This letter reports on room temperature sub-THz detection using self-switching diodes based on an AlGaN/GaN heterostructure on a Si substrate. By means of free-space measurements at 300 GHz, we demonstrate that the responsivity and noise equivalent power (NEP) of sub-THz detectors based on planar...
