Effective properties of metamaterials using inverse methods

Laetitia Roux, Christian Audoly, Anne-Christine Hladky, Nicole Kessissoglou

Metamaterials can be engineered for noise and vibration control due to their ability to manipulate waves in band gaps and due to local resonance effects. Metamaterials are often characterised in terms of effective parameters derived from an equivalent homogeneous medium. This work compares two…

MIMO in tunnel: impact of polarization and array orientation on the channel characteristics

Frédéric Challita, Pierre Laly, M. Lienard, Davy Gaillot, Pierre Degauque, Jose-Maria Molina-Garcia-Pardo, Wout Joseph

Polarimetric characteristics of the propagation channel in a straight tunnel and in a frequency band around 1.3 GHz, are deduced from measurements using a real-time MIMO channel sounder. Emphasis is on the cross-polarization discrimination factor and, for a MIMO configuration, on the correlation…

An indoor variance-based localization technique utilizing the UWB estimation of geometrical propagation parameters

Brecht Hanssens, David Plets, Emmeric Tanghe, Claude Oestges, Davy Gaillot, M. Lienard, Taoyong Li, Heidi Steendam, Luc Martens, Wout Joseph

A novel localization framework is presented based on Ultra-Wideband (UWB) channel sounding, employing a triangulation method using the geometrical properties of propagation paths, such as time-delay of arrival, angle of departure, angle of arrival, and their estimated variances. In order to extract…

Transmission gaps, trapped modes and Fano resonances in Aharonov-Bohm connected mesoscopic loops

T. Mrabti, Z. Labdouti, O. El Abouti, E. H. El Boudouti, F. Fethi, Bahram Djafari-Rouhani

A simple mesoscopic structure consisting of a double symmetric loops coupled by a segment of length do in the presence of an Aharonov-Bohm flux is designed to obtain transmission band gaps and Fano resonances. A general analytical expression for the transmission coefficient and the density of…

Study of the spectral bandwidth of a double-pass acousto-optic system

Justine Champagne, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

Acousto-optic tunable filters are known as efficient instruments for spectral and spatial filtering of light. In this paper, we analyze the bandwidth dependence of a double-pass filter. The interaction geometry chosen allows the simultaneous diffraction of the ordinary and the extraordinary optical…

High-Pass Sub-mm Wave Filtering by Woven Textile Metamaterials

Ludovic Burgnies, Camille Huppe, Guillaume Ducournau, Cedric Cochrane, Francois Rault, Vladan Koncar, Eric Lheurette

Textile metamaterials produced by a weaving of metallic and dielectric yarns are considered for filtering operations in the sub-millimeter hand. A woven metamaterial was designed by parametric simulations aimed at producing a high-pass filter with a cutoff frequency at around 500 GHz above a high-…

Rayleigh Waves in Phononic Crystal Made of Multilayered Pillars: Confined Modes, Fano Resonances, and Acoustically Induced Transparency

M. Oudich, Bahram Djafari-Rouhani, B. Bonello, Yan Pennec, S. Hemaidia, F. Sarry, D. Beyssen

We present a design of phononic crystal based on pillars distributed on a substrate surface in which each pillar is constructed by a periodic stacking of PMMA and silicon layers. The pillar behaves like a one-dimensional phononic crystal which allows the creation of band gaps that prohibits wave…

Cyber Security of the Railway wireless system: detection, decision and Human-in-the-Loop

Christophe Gransart, Virginie Deniau, Eric Pierre Simon, Anthony Fleury, Stéphane Lecoeuche, Emilie Masson, Patrick Millot

The networks used in the Railway domain are usually heterogeneous, not enough protected and not fitted to the usual Cyber Security requirements in terms of sustainability, protection and attack detection. Furthermore, the quick evolution of the telecommunication means, the threats and the…

Unambiguous real-time terahertz frequency metrology using dual 10 GHz femtosecond frequency combs

Oliver Kliebisch, Dirk Heinecke, S Barbieri, Giorgio Santarelli, Hua Li, Carlo Sirtori, Thomas Dekorsy

Terahertz frequency metrology by radio frequency downconversion using femtosecond optical sampling relies on the harmonic factor retrieval between the terahertz frequency and the optical sampling rate. At typical femtosecond laser repetition rates, this imposes an ambiguity for frequency metrology…
