Secure Transmission in NOMA Systems: An Efficient Resource Allocation Strategy Using Deep Learning

Miled Alam, Abdul Karim Gizzini, Laurent Clavier

Deep learning (DL) algorithms have been widely integrated in various aspects of wireless communications research. In this paper, we investigate, in an Internet of Things context, the secrecy energy-efficiency (SEE) of a multi-user downlink non-orthogonal multiple access (NOMA) system in the…

In situ growth of N-doped carbon nanotubes from the products of graphitic carbon nitride etching by nickel nanoparticles

Mariusz Pietrowski, Emilia Alwin, Michał Zieliński, Sabine Szunerits, Agata Suchora, Robert Wojcieszak

The in situ growth of N-doped multi-walled carbon nanotubes (N-MWCNTs) from the products of graphitic carbon nitride (g-C$_3$N$_4$) etching by Ni nanoparticles in a hydrogen atmosphere has been confirmed for the first time. During the etching process of g-C$_3$N$_4$, the building blocks, notably…

Bound states in the continuum and long-lived electronic resonances in mesoscopic structures

Leonard Dobrzyński, Housni Al-Wahsh, Abdellatif Akjouj, Eman A Abdel-Ghaffar

A. bound state eigenfunction is defined here to be strictly localized within a subspace of the structure under study and has no decreasing behavior. Its eigenwavelength can be within state continua. Bound states in the continuum (BICs) and long-lived resonances have become a unique way to produce…

Self-sustained optomechanical state destruction triggered by the Kerr nonlinearity

A Delattre, I Golokolenov, R Pedurand, Xin Zhou, A Fefferman, E Collin

Cavity optomechanics implements a unique platform where moving objects can be probed by quantum fields, either laser light or microwave signals. With a pump tone driving at a frequency above the cavity resonance, self-sustained oscillations can be triggered at large injected powers. These limit…

Thermoelectric characterization of crystalline nano-patterned silicon membranes

Hafsa Ikzibane, Akash Patil, Jon Canosa Diaz, Etienne Okada, Etienne Blandre, Emmanuel Dubois, Jean-François Robillard

Research towards efficient and environmentally friendly thermoelectrics proposes silicon nanostructures as possible candidates through reduction of the phononic thermal conductivity. However, there is scarce literature about experimental measurements of the thermoelectric figure-of-merit zT on…

Low Dielectric Filling Factor Millimeter-Wave Photonic Crystal Resonator Micromachined From NTD High-Resistivity Silicon

Stephen Hanham, Jan-Hendrik Buchholz, Horst Fischer, Uwe Gollor, Jonas Lehmke, Wolfgang Wischmann, Indra Ghosh, Enrico Lia, Benjamin Walter, Fuanki Bavedila, Marc Faucher, Andrew Gregory, Leif Jensen, Rüdiger Follmann

This article introduces a millimeter-wave electromagnetic (EM) bandgap (EBG) resonator, commonly referred to as a photonic crystal (PC) resonator (PCR), designed for use in a 45-GHz ultralow phase noise MMIC oscillator. The novel 2-D slab PCR design utilizes a higher order resonant mode, which has…

Directional Acoustic Bulk Waves in a 2D Phononic Crystal

Pierre A Deymier, Jérôme O Vasseur, Keith Runge, Krishna Muralidharan, Alexander Khanikaev, Andrea Alù

We used the transfer matrix method to investigate the conditions supporting the existence of directional bulk waves in a two-dimensional (2D) phononic crystal. The 2D crystal was a square lattice of unit cells composed of rectangular subunits constituted of two different isotropic continuous media…
