Low-complexity feature extraction unit for “Wake-on-Feature” speech processing

Simon Lecoq, Jean Le Bellego, Angel Gonzalez, Benoit Larras, Antoine Frappé

In the context of energy-constrained automatic speech recognition, a modeling and simulation tool is presented to evaluate the hardware complexity of a feature extraction unit. The objective is to evaluate the minimal amount of features necessary for voice-activity detection, considering limited...

High-Pass Sub-mm Wave Filtering by Woven Textile Metamaterials

Ludovic Burgnies, Camille Huppe, Guillaume Ducournau, Cedric Cochrane, Francois Rault, Vladan Koncar, Eric Lheurette

Textile metamaterials produced by a weaving of metallic and dielectric yarns are considered for filtering operations in the sub-millimeter hand. A woven metamaterial was designed by parametric simulations aimed at producing a high-pass filter with a cutoff frequency at around 500 GHz above a high-...

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...

Phononics

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

Phononics: Interface Transmission Tutorial Book Series provides an investigation of modern systems that includes a discrete matrix description. Classical continuous systems relying on the use of differential equations are recalled, showing that they generally have a specific limit on their...

Acoustic analogue of electromagnetically induced transparency and Autler-Townes splitting in pillared metasurfaces

Yabin Jin, Yan Pennec, Bahram Djafari-Rouhani

Electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) originating from multilevel atomic systems have similar transparency windows in transmission spectra which causes confusion when discriminating between them, despite the difference in their physical mechanisms. Indeed...

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...

Study of the spectral bandwidth of a double-pass acousto-optic system

Justine Champagne, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

Acousto-optic tunable filters are known as efficient instruments for spectral and spatial filtering of light. In this paper, we analyze the bandwidth dependence of a double-pass filter. The interaction geometry chosen allows the simultaneous diffraction of the ordinary and the extraordinary optical...

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),...

Indoor 100 Gbit/s THz data link in the 300 GHz band using fast photodiodes

Vinay Kumar Chinni, Malek Zegaoui, Christophe Coinon, X. Wallart, Emilien Peytavit, Jean-Francois Lampin, P. Szriftgiser, Mohammed Zaknoune, Guillaume Ducournau

This paper presents recent achievements towards 100 Gbit/s data links for future 300 GHz communication systems with the new IEEE 802.15.3d standard. Resonant photodiodes structures, and their application for QAM-16 data links in the THz range are shown in indoor scenario.
