Impact of Transducer Aspect Ratio on the performance of AlN Hybrid SAW/BAW Resonators

S. Barsoum, A. Schembri, M. Bernard, A. Lefevre, M. Bousquet, A. Reinhardt, T. Laroche, S. Ballandras, B. Dubus

In this study, we investigate the impact of the aspect ratio of transducers on the electromechanical coupling factor k2t of hybrid SAW/BAW (HSB) resonators. Finite element calculations of the harmonic admittance suggest that the optimum k2t for the two modes of interest of these devices, are...

6.9 GHz Film Bulk Acoustic Resonator based on Pulsed Laser Deposited LiNbO3 Film

L.C. Sauze, N. Vaxelaire, R. Templier, F. Pierre, C. Maeder-Pachurka, J. Delprato, D. Remiens, G. Rodriguez, M. Bousquet, F. Dupont

In this work, 200 nm-thick LiNbO 3 layers have been grown on Ru/Si and Pt/Si substrates using an industrialized Pulsed Laser Deposition (PLD) system. Film’s properties have been investigated by means of X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), and...

Terahertz time domain spectroscopy of a single split ring resonator coupled to an amino acid crystal

Théo Hannotte, Adrien Pillet, Noureddin Osseiran, Jean-Francois Lampin, Romain Peretti

Split Ring Resonators (SRRs) have been used in large arrays to interact with objects much smaller than the wavelength in the terahertz range. Using arrays of SRRs facilitates the measurements, but prevents one from extracting accurate information regarding the object properties in this frequency...

Multi-user downlink NOMA systems aided by an ambient backscatter device: achievable rate region and energy-efficiency maximization

Hajar El Hassani, Anne Savard, E. Veronica Belmega, Rodrigo C. De Lamare

In this paper, we investigate the energy efficiency of a multiuser downlink Non-Orthogonal Multiple Acess (NOMA) system aided by an ambient backscatter device that modulates its own information by reflecting the incident signal coming from the NOMA transmitter. Because of the multiplicative...

Formation and highly directional output of long-lived resonances in photonic comblike structures

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

Bound states in the continuum (BICs) and long-lived resonances have become a unique way to produce the extreme localization of light waves. In this paper, we present a theoretical demonstration of BICs and long-lived resonances in photonic comblike structures with two semi-infinite leads, together...

Asynchronous WPNC With DFT Precoding and Symbol-Spaced Processing

Petr Hron, Jan Sykora, Laurent Clavier

This letter addresses the problem of asynchronous reception in a 2-source Hierarchical MAC (H-MAC) in the context of a Wireless Physical Layer Network Coded (WPNC) system with a Hierarchical Decode and Forward (HDF) relaying strategy. In this work, we assume fractional symbol duration time delays...
