An extension of the RiMAX multipath estimation algorithm for ultra-wideband channel modeling

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

This work presents an extension of the high-resolution RiMAX multipath estimation algorithm, enabling the analysis of frequency-dependent propagation parameters for ultra-wideband (UWB) channel modeling. Since RiMAX is a narrowband algorithm, it does not account for the frequency-dependency of the...

Ultra-low loss ridge waveguides on lithium niobate via argon ion milling and gas clustered ion beam smoothening

Shawn Yohanes Siew, Eric Jun Hao Cheung, Haidong Liang, Andrew Bettiol, Noriaki Toyoda, Bandar Alshehri, El Hadj Dogheche, Aaron J. Danner

Lithium niobate's use in integrated optics is somewhat hampered by the lack of a capability to create low loss waveguides with strong lateral index confinement. Thin film single crystal lithium niobate is a promising platform for future applications in integrated optics due to the availability...

Magnetodielectric Nanocomposite Polymer-Based Dual-Band Flexible Antenna for Wearable Applications

Z. Hamouda, Jean-Luc Wojkiewicz, Alexander A. Pud, Lamine Kone, Said Bergheul, Tuami Lasri

One of the major challenges in wireless communication technologies is the antenna design. In this paper, a wide-band flexible antenna made by covering a Kapton substrate with a flexible magnetodielectric polymer-based nanocomposite layer is proposed. This novel magnetodielectric polymer-based...

Highly Sensitive Surface Acoustic Wave Magnetic Field Sensor Using Multilayered TbCo2/FeCo Thin Film

Aurelien Mazzamurro, Abdelkrim Talbi, Yannick Dusch, Omar Elmazria, Philippe Pernod, Olivier Bou Matar, Nicolas Tiercelin

Over the last decades, the use of Surface Acoustic Waves (SAW) has emerged as a promising technology in many applications such as filters, signal processing but also sensors. We report the fabrication and the characterization of a SAW delay line magnetic field sensor using uniaxial multi-layered...

Impact of unintentional oxygen doping on organic photodetectors

Julie Euvrard, Amelie Revaux, Alexandra Cantarano, Stephanie Jacob, Antoine Kahn, Dominique Vuillaume

Oxygen plasma is a widely used treatment to change the surface properties of organic layers. This treatment is particularly interesting to enable the deposition from solution of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) on top of the active layer of organic solar cells or...

Graphene FETs Based on High Resolution Nanoribbons for HF Low Power Applications

David Mele, Sarah Mehdhbi, Dalal Fadil, Wei Wei, Abdelkarim Ouerghi, Sylvie Lepilliet, Henri Happy, Emiliano Pallecchi

In this paper we present high frequency field effect transistors based on graphene nanoribbons arrays (GNRFETs). The nanoribbons serve as a channel for the transistors and are fabricated with a process based on e-beam lithography and dry etching of high mobility hydrogen intercalated epitaxial...

Extrinsic capacitance extraction for GaAs and GaN FETs from low to high temperatures

Mohammad A. Alim, Ali A. Rezazadeh, Christophe Gaquière, Giovanni Crupi

The main aim of this article is to present an experimental analysis of the thermal influence on the positive derivatives of the real parts of impedance parameters against frequency (PDRZ) for microwave GaN and GaAs based HEMTs. The PDRZ effect is investigated with respect to temperature by both...

Multimodal microscopy test standard for scanning microwave, electron, force and optical microscopy

Olaf C. Haenssler, M. F. Wieghaus, A. Kostopoulos, G. Doundoulakis, E. Aperathitis, S. Fatikow, G. Kiriakidis

We report on measurement results of a test standard suitable for different microscopic modalities. These findings were obtained by a multimodal hybrid microscope, which requires various calibration methods, also in terms of its further use as a tool in a nanorobotic environment. A Scanning Probe...

GaN-Based Laser Wireless Power Transfer System

Carlo de Santi, Matteo Meneghini, Alessandro Caria, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Boris Kalinic, Tiziana Cesca, Gaudenzio Meneghesso, Enrico Zanoni

The aim of this work is to present a potential application of gallium nitride-based optoelectronic devices. By using a laser diode and a photodetector, we designed and demonstrated a free-space compact and lightweight wireless power transfer system, whose efficiency is limited by the efficiency of...
