Towards Novel Researcher Tooling Based on Multimodal Analytics

Much of educational research today employs a complex mixture of qualitative and quantitative analyses, both during the exploratory and confirmatory phases. However, researchers are still stuck with tools that were developed mainly for single-perspective re ...

Design and experimental validation of an active acoustic liner for aircraft engine noise reduction

Hervé Lissek, Romain Boulandet, Sami Driss Karkar, Gaël Matten

The use of acoustic liners in aviation industry is a quite common solution for reducing the engines acoustic emissions. Although the current solutions based on single or multilayer liners are efficient and compact for the mid and high frequencies, noise mi ...

Modulated scattering technique in the terahertz domain enabled by current actuated vanadium dioxide switches

Juan Ramon Mosig, Anja Skrivervik, Mihai Adrian Ionescu, Wolfgang Amadeus Vitale, Michele Tamagnone, Santiago Capdevila Cascante

The modulated scattering technique is based on the use of reconfigurable electromagnetic scatterers, structures able to scatter and modulate an impinging electromagnetic field in function of a control signal. The modulated scattering technique is used in a ...

Enabling High Frequency Reconfigurable Functions with Graphene

Clara-Fausta Moldovan

As the scaling of complementary metal-oxide-semiconductor (CMOS) technology is reaching fundamental limitations, novel device concepts and materials have started to be investigated to overcome the scaling challenges for integrated circuits. Graphene has be ...

Fine Pitch 3D-TSV Based High Frequency Components for RF MEMS Applications

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Josef Weber

The development of interconnections suitable for radio- frequency (RF) and millimeter-wave (mm-wave) applications is of foremost importance for the feasibility of high-quality substrate-integrated devices. For this purpose, we introduce and validate the te ...

A nanoscale gigahertz source realized with Josephson scanning tunneling microscopy

Klaus Kern, Markus Etzkorn, Maximilian Assig, Matthias Alexander Eltschka

Using the AC Josephson effect in the superconductor-vacuum-superconductor tunnel junction of a scanning tunneling microscope (STM), we demonstrate the generation of GHz radiation. With the macroscopic STM tip acting as a lambda/4-monopole antenna, we first ...

Towards Implementation of Motor Imagery using Brain Connectivity Features

Ricardo Andres Chavarriaga Lozano, José del Rocio Millán Ruiz, Huaijian Zhang

This study aims to explore modulation of the connectivity pattern when people perform left hand versus right hand motor imagery and probe the feasibility of adopting connectivity information to discriminate these tasks. Nine subjects were recorded with 16- ...

Properties and Printability of Inkjet and Screen-Printed Silver Patterns for RFID Antennas

Nico de Rooij, Francisco Molina Lopez, Danick Briand, Jinyu Jason Ruan

We report the modeling, and geometrical and electrical characterization, of inkjet and screen-printed patterns on different polymeric substrates for use as antennas in radio-frequency identification (RFID) applications. We compared the physical and electri ...

MoS2 Transistors Operating at Gigahertz Frequencies

Yusuf Leblebici, Andras Kis, Clemens Benedict Nyffeler, Dominik Sebastian Lembke, Daria Krasnozhon

The presence of a direct band gap1-4 and an ultrathin form factor5 has caused a considerable interest in two-dimensional (2D) semiconductors from the transition metal dichalcogenides (TMD) family with molybdenum disulfide (MoS2) being the most studied repr ...

Intra-particle dynamics and the impact response of granular chains

Alessandro Spadoni, Bart Van Damme

Low-frequency waves generated by an impact on an isostatic granular medium with vanishing confinement pressure are theorized to depend on rigid-particle collisions. According to this model, an impact generates a solitary wave spanning several particle diam ...
