Wide-Angle Reflective Terahertz Beam Steering Metasurface Based on Cross-Polarization Conversion

Mengyao Li, Zhonghua Gu, Cheemalamarri Hemanth Kumar, Nanhan Liu, Frédéric Dutin, Pascal Szriftgiser, Guillaume Ducournau, Prakash Pitchappa

The terahertz (THz) frequency range is considered an important spectrum for future six-generation communication. However, the high propagation losses and poor penetration inherent to THz waves restricted its development. Wavefront manipulation techniques for beam steering to redirect the…

Microcavités pour composants RF-SOI-CMOS ultra-rapides pour application 5G et delà, Microcavities for ultra-fast RF-SOI-CMOS components for 5G applications and beyond

Daniel Gheysens

Le développement des standards de communication mobile impose des exigences toujours plus strictes aux commutateurs radiofréquence (RF), notamment en termes de bande passante, pertes, linéarité et bruit. La technologie RF SOI-CMOS partiellement déplétée s’est imposée comme la solution dominante…, The development of mobile communication standards imposes increasingly stringent requirements on radio frequency (RF) switches, particularly in terms of bandwidth, losses, linearity, and noise. Partially depleted SOI-CMOS RF technology has emerged as the dominant solution thanks to an optimal…

Quantum Coherent Transport of 1D Ballistic States in Second-Order Topological Insulator Bi4⁢Br4

Jules Lefeuvre, Masaru Kobayashi, Gilles Patriarche, Nathaniel Findling, David Troadec, Meydi Ferrier, Sophie Guéron, Hélène Bouchiat, Takao Sasagawa, Richard Deblock

We investigate quantum transport in micrometer-sized single crystals of Bi$_4$Br$_4$, a material predicted to be a second-order topological insulator. 1D topological states with long phase coherence times are revealed via the modulation of quantum interferences with magnetic field and gate voltage…
