Neuromorphic Coincidence Detector for Interaural Time Difference Encoding and Sound DOA Estimation

Eugénie Dalmas, François Danneville, Michael Bocquet, Christophe Loyez

Eight decades ago, the medial superior olive (MSO) responsible for the extraction of the interaural time difference (ITD) was described as a combination of coincidence detection neurons and delay lines by Jeffress, a model largely used in spiking sound source localization systems. Coincidence…

TileChain: A Blockchain-Based Framework for Security Service Management For Vehicular Communications

Ahmed Didouh, Anthony Bahadir Lopez, Houda Labiod, Yassin El Hillali, Atika Rivenq, Mohammad Abdullah Al Faruque

Vehicular communications have become essential for functional and road safety purposes due to the development of vehicle fleets. However, these communications have made vehicles more vulnerable to cyber-attacks. The security of data exchanges in vehicular networks currently relies on a centralized…

Integrated twisted bilayer graphene photonic upconverter for D-Band wireless links

Alberto A. Montanaro, A. Boschi, Guillaume Ducournau, Vaidotas Mišeikis, S. Soresi, M.G.L. Frecassetti, P. Galli, Henri Happy, S. Pezzini, C. Coletti, Marco Romagnoli, V. Sorianello

We report a compact D-band graphene photonics-based upconverter at 140 GHz for next generation 6G networks. We show 10Gb/s QPSK and 4Gb/s 16QAM transmission exploiting ultra-broadband ( 180 GHz ) operation of CVD-grown large-angle twisted-bilayer-graphene.

Broadband high-contrast-grating-type waveplates for the terahertz range

Surya Revanth Ayyagari, Andreas K Klein, Simonas Indrišiūnas, Vytautas Janonis, Daniil Pashnev, Abdu Subahan Mohammed, Guillaume Ducournau, Andreas Stöhr, Irmantas Kašalynas

The high-contrast-grating waveplates utilizing high contrast between silicon and air refractive indexes were developed in order to perform as a quarter wave and a half wave plate in the selected THz frequency range. The waveplates possessed anti-reflective properties due to the specific inclination…

Tilted columnar metal film as transducer of transverse coherent acoustic phonons in picosecond acoustics

A. Chargui, N. Martin, G. Ferro, Arnaud Devos

Picosecond acoustics has been widely used to study thin film elasticity, hypersound attenuation, and adhesion of thin films to substrates. A major limitation of the technique is its restriction to only longitudinal waves. Although work has been reported on the ultrafast generation and detection of…
