Elastic Metasurfaces for Deep and Robust Subwavelength Focusing and Imaging

Yabin Jin, Wan Wang, Abdelkrim Khelif, Bahram Djafari-Rouhani

Metasurfaces are planar metamaterials with a flat surface and a subwavelength thickness that are able to shape arbitrary wave fronts such as focusing or imaging. There is a broad interest in the literature about subwavelength focusing and imaging based on bulk metamaterials while the utilization of…

Radiation environment and doses on Mars at Oxia Planum and Mawrth Vallis: support for exploration at sites with high biosignature preservation potential

F. da Pieve, G. Gronoff, J. Guo, C. J. Mertens, L. Neary, B. Gu, N. E. Koval, J. Kohanoff, A. C. Vandaele, F. Cleri

The first human missions on MARS will likely involve several astrobiology‐driven science operations, at sites with high biosignature preservation potential. Here, we present a study of the radiation environment induced by Galactic Cosmic Rays and Solar Energetic Particles at OXIA PLANUM, landing…

Bandpass NGD function design for 5G microwave signal delay synchronization application

Sébastien Lalléchère, Lala Rajaoarisoa, Laurent Clavier, Raul Sanchez Galan, Blaise Ravelo

This paper introduces a design method of simple bandpass (BP) negative group delay (NGD) topology. The fundamental specifications of BP NGD function are defined. The NGD passive topology consists of parallel resistance associated with an open-ended microstrip stub. The NGD properties and…

Aggregated Euclidean Distances for a Fast and Robust Real-Time 3D-MOT

Rahmad Sadli, Mohamed Afkir, Abdenour Hadid, Atika Rivenq, Abdelmalik Taleb-Ahmed

Autonomous driving systems must have the ability to monitor the kinematic behaviour of multiple obstacles. Therefore, 3D multi-object tracking (3D-MOT) is one of the crucial modules in autonomous driving to detect the presence of potential hazard movements such as human operated vehicles and…

20 Gbit/s 306 GHz link enabled by Yagi-Uda antenna

Guillaume Ducournau, Fabio Pavanello, Aritrio Bandyopadhyay, Cybelle Belem-Gonçalves, Frédéric Gianesello, Cyril Luxey, Emilien Peytavit, Jean-Francois Lampin, Malek Zegaoui, Mohammed Zaknoune

We report on the use of a Yagi-Uda antenna on polymer substrate used in a 306 GHz-20 Gbit/s real-time data link for indoor applications. The Yagi-Uda antenna is described and the validation of the THz link is obtained in amplitude modulation mode and using QAM-16 signals (32 Gbit/s).

Nanoprobe study of the electric field driven insulator-to-metal transition in GaMo4S8

H. Koussir, Isabelle Lefebvre, Maxime Berthe, B. Grandidier, Pascale Diener, J. Tranchant, Benoit Corraze, Etienne Janod, Laurent Cario

The resistive switching observed under electric pulses in Mott materials has a high potential for micro and nanoelectronics. Here we report on the study of the resistive switching observed at the surface of single crystals of the canonical Mott semiconductor GaMo4S8. The study is made using a…

H-Band Substrate-Integrated Discrete-Lens Antenna for High Data Rate Communication Systems

Kossaila Medrar, Loïc Marnat, Laurent Dussopt, Cybelle Belem-Gonçalves, Guillaume Ducournau, Cyril Luxey, Frédéric Gianesello

A substrate-integrated discrete-lens antenna manufactured in standard printed-circuit-board (PCB) technology is demonstrated in H-band (225-325 GHz). The arrays composed of phase-shifting unit cells and a waveguide-fed planar focal source are designed on a single PCB stack with five metal layers…
