Tunable topologically protected waveguiding in auxetic nonlinear metamaterials

M. Morvaridi, F. Bosia, M. Brun, V.F. Dal Poggetto, A.S. Gliozzi, M. Miniaci, C. Croenne, N.M. Pugno, G. Carta

In this paper, we discuss the possibility of achieving tunable topologically protected edge modes through the application of uniaxial prestrain in an auxetic metamaterial. The proposed structure consists of a thin slab with oriented cuts in a hexagonal lattice, where topologically protected band…

FT-IR detection of DMMP on TiO 2 -Modified Porous Silicon Substrates

Warda Raiah, M. Guendouz, Parastesh Pirasteh, Vincent Thomy, Joël Charrier, Yannick Coffinier

In this study, we present a new chemical sensor based on a functionalized porous silicon and sensitive to dimethyl methyl phosphonate (DMMP), a simulant of sarin gas, known as one of the most toxic warfare agents. The porous silicon was prepared by anodising a boron-doped p-Si (100) wafer. A metal…

Enabling Low-Power Signature Recognition for the IoT with SLIF neurons

Guillaume Marthe, Claire Goursaud, Laurent Clavier

Energy constraints are still a significant challenge in numerous IoT applications, particularly due to the excessive power consumption of microcontrollers. To overcome this limitation, novel circuit designs have been introduced, with the integration of spiking neurons and analog computing emerging…

Thermoelectric Properties of Benzothieno-Benzothiophene Self-Assembled Monolayers in Molecular Junctions

Sergio Gonzalez-Casal, Rémy Jouclas, Imane Arbouch, Yves Geerts, Colin van Dyck, Jérôme Cornil, Dominique Vuillaume

We report a combined experimental (C-AFM and SThM) and theoretical (DFT) study of the thermoelectric properties of molecular junctions made of self-assembled monolayers on Au of thiolated benzothieno-benzothiophene (BTBT) and alkylated BTBT derivatives (C8-BTBT-C8). We measure the thermal…

Fault detection and localization in unshielded twisted pair cable based on observability analysis and reflectometry experimental measurements.

Hermine Judith Idellette Som, Vincent Cocquempot, Virginie Degardin

In this paper, an efficient method is proposed for detecting and locating a soft fault, i.e. a physical degradation, in a Y -shaped network of unshielded twisted pair cables. The method uses jointly the observability analysis and time-frequency domain reflectometry experimental measurements. The…
