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…

A fully flexible circuit implementation of clique-based neural networks in 65-nm CMOS

Benoit Larras, Paul Chollet, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks implement low- complexity functions working with a reduced connectivity be- tween neurons. Thus, they address very specific applications operating with a very low energy budget. This paper proposes a flexible and iterative neural architecture able to implement multiple…

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…

Digital complex delta-sigma modulators with highly configurable notches for multi-standard coexistence in wireless transmitters

Razvan-Cristian Marin, Antoine Frappé, Andreas Kaiser

This paper presents a complex delta-sigma modu-lator (CDSM) designed for integration in a digital transmitter chain targeting multi-standard coexistence with nearby receivers. The use of a DSM has the advantage of increased performance in terms of signal-to-noise-ratio in the band of interest.…

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

H. Sanchez-Martin, J. Mateos, J. A. Novoa, J. A. Delgado-Notario, Y. M. Meziani, S. Perez, H. Theveneau, Guillaume Ducournau, Christophe Gaquière, T. Gonzalez, I. Iniguez-De-La-Torre

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…
