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...

Deep Learning-based Successive Interference Cancellation to Improve Uplink in LoRa Networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Mohammed Mallik, Virginie Deniau, Laurent Clavier

This paper presents a deep learning-based successive interference cancellation (SIC) scheme to improve the uplink in the LoRa Network. The proposed receiver can decode simultaneous transmissions from multiple users on the same frequency channel with the same spreading factor. The objective of the...

Interdigitated-comb piezoelectric phononic crystals for innovative SAW devices

R. Alcorta Galván, C. Croënne, B. Dubus, E. Eustache, A. Ngabonziza, A.-C. Hladky-Hennion

In this paper, piezoelectric phononic crystals made up of interdigitated combs in floating potential condition are studied. Calculation of the dispersion curves shows that, in addition to Bragg bandgaps due to the presence of periodic electrodes, supplementary bandgaps are present corresponding to...

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...

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...
