Exceptional Points and Skin Modes in Non-Hermitian Metabeams

Runcheng Cai, Yabin Jin, Yong Li, Timon Rabczuk, Yan Pennec, Bahram Djafari-Rouhani, Xiaoying Zhuang

We present a non-Hermitian metabeam exhibiting an exceptional point (EP) induced by enforcing parity-time (PT) symmetry through applied external forces. The EP is formed by the hybridization of two flexural wave modes and its output displacement is enhanced by attaching two pillars on top of the…

High speed, antenna-enhanced 10.3 μm quantum cascade detector

G. Quinchard, C. Mismer, M. Hakl, J. Pereira, Quyang Lin, Sylvie Lepilliet, V. Trinité, A. Evirgen, Emilien Peytavit, J. Reverchon, Jean-Francois Lampin, S Barbieri, A. Delga

The strong potential of intersubband detectors in the field of mid-infrared photodetection places this technology as a relevant alternative to HgCdTe detectors in the race for ultrafast operation. While their extremely short photocarrier's lifetime opens up possibilities of detection beyond…

Structure of deposits formed by drying of droplets contaminated with Bacillus spores determines their resistance to rinsing and cleaning

Maureen Deleplace, Heni Dallagi, Thomas Dubois, Elodie Richard, Anna Ipatova, Thierry Bénézech, Christine Faille

The formation of deposits by evaporation of droplets contaminated by Bacillus spores was investigated, focusing on the role of spore and material properties. Droplets containing hydrophilic to hydrophobic spores were deposited on materials (stainless steels, polypropylene, glass). The presence of…

Unidirectional Coherent Phonon Emission in an Optomechanic Nanobeam Containing Coupled Cavities

Alexander Korovin, Yan Pennec, Bahram Djafari-Rouhani

Nonreciprocal phonon emission is predicted theoretically from the coherent excitation of two coupled optomechanical cavities arranged along a phoxonic crystal nanobeam. The latter consists of a periodic array of holes and stubs and exhibits simultaneous photonic and phononic bandgaps. It is shown…

Optimized ohmic contacts for InAlGaN/GaN HEMTs

Pierre Ruterana, Marie Pierre Chauvat, Magali Morales, Farid Medjdoub, Piero Gamarra, Christian Dua, Sylvain Delage

In this work, we have carried out a detailed transmission electron microscopy investigation on ohmic contacts in InAl GaN/GaN high electron mobility transistors consisting of Ti/Al/Ni/Au deposited by evaporation electron beam followed by a rapid thermal annealing at 875°C for 30s under N2…

De la théorie à la pratique dans l’enseignement du traitement du signal : initiation à la recherche

Lynda Chehami, Nikolay Smagin, Jamal Assaad, Pierre Campistron, Frédéric Jenot, Emmanuel Moulin

Le débat entre la théorie et la pratique dans l'enseignement sur l'importance de chacun comme base de la formation en Master existe depuis plusieurs années. Ce lien est souvent sous-évaluée et on a tendance à oublier que de la théorie naît la pratique et que la pratique est basée sur la…

10. Incremental learning of convolutional neural networks in bioinformatics

Wafa Mousser, Salima Ouadfel, Abdelmalik Taleb-Ahmed

In recent years, convolutional neural networks (CNNs) have been widely used in various computer visual recognition tasks and then extensively applied for medical images, particularly for computer-aided diagnosis. Despite this success, CNNs suffer from a catastrophic forgetting issue, making it…

Impact of forward body-biasing on ultra-low voltage switched-capacitor RF power amplifier in 28 nm FD-SOI

Guillaume Tochou, Andreia Cathelin, Antoine Frappé, Andreas Kaiser, Jan Rabaey

The Switched-Capacitor Power Amplifier (SCPA) has become a key enabler for modern wireless communication because of its high efficiency, high linearity, and high integrability. This paper discusses the impact of the extended Forward Body-Biasing (FBB) feature in 28 nm FD-SOI technology on Ultra-Low…
