Absorptivity Modulation with Salisbury-Inspired Structures for X-Band

Xhoandri Lleshi, Thi Quynh van Hoang, Paolo Martins, Brigitte Loiseaux, Didier Lippens

Absorptivity control is a very desired feature in many RF applications as it allows enhancing electromagnetic performances such as antenna radiation patterns and reducing radar cross section. In this paper, two Salisbury-inspired structures with absorption level of 20% and 50% in X-band frequencies...

[Seminar] Tunability of electrically controlled piezoelectric phononic crystals

Anne-Christine Hladky

Phononic Crystals (PCs) (i.e. periodic arrangements of several materials) have received a great deal of interest for the last two decades because of the unusual properties that they can exhibit. Classically, depending on material properties and geometrical arrangement, PCs can produce band gaps, i....

GAP(111)B-SE Surface for TMD epitaxial growth

Niels Chapuis, Christophe Coinon, D. Deresmes, Xavier Wallart

Over the past few years, 2D-Transition Metal Dichalcogenides (TMDs) have revealed great potential for optoelectronics and nanoelectronics devices, thanks to their exceptional properties, not encountered in other materials. They can be grown by van der Waals epitaxy allowing the use of materials...

SiGe Circuits for Future LEO Constellations

Marc Margalef-Rovira, N. Defrance, Guillaume Ducournau

This work presents an overview of the current state-of-the-art Power Amplifiers and Low-Noise amplifiers in the 40–75 GHz frequency band (i.e., V -band). These RF blocks are critical for the development of future LEO constellations that have recently begun to target these frequencies. Special...

High Data Rate OOK Wireless Link at 300 GHz Band through Metasurface-based Filters: Analysis, Design, and Experiment

Daniele Pirrone, Antonio Ferraro, Dimitrios Zografopoulos, Pascal Szriftgiser, Guillaume Ducournau, Romeo Beccherelli, Walter Fuscaldo

The capabilities of frequency-selective surface (FSS) as free-space filters for wireless communications in the 300 GHz band are here demonstrated experimentally. The presence of a filter plays a key role to protect wireless communications from out-of-band interference without resorting to...

Improving ViBe-based Background Subtraction Techniques Using RGBD Information

Ihssane Houhou, Athmane Zitouni, Yassine Ruichek, Salah Eddine Bekhouche, Abdelmalik Taleb-Ahmed

In this paper, we propose a framework for improving Background Subtraction techniques. This framework is based on two types of data, RGB and Depth. Our study stands for obtaining preliminary results of the background segmentation using Depth and RGB channels independently, then using an algorithm...
