Geometrically Balanced Metal Detector Based on Optimized Frequencies and Spatial Phase Profile Responses to Discriminate Different Metal Rods Features

Yves Perriard, Chafic Abu Antoun

Inductive detection with double-balanced coils and a spatial phase profile were used to identify copper and steel rods in a composite target. The electromagnetic detection system was designed and validated using a dipole model. Simulations and experiments ...

High-Kinetic-Inductance Superconducting Nanowire Resonators for Circuit QED in a Magnetic Field

Pasquale Scarlino

We present superconducting microwave-frequency resonators based on NbTiN nanowires. The small cross section of the nanowires minimizes vortex generation, making the resonators resilient to magnetic fields. Measured intrinsic quality factors exceed 2×105 in ...

Dipole codes attractively encode glue functions

Massimo Mastrangeli

Dipole words are sequences of magnetic dipoles, in which alike elements repel and opposite elements attract. Magnetic dipoles contrast with more general sets of bonding types, called glues, in which pairwise bonding strength is specified by a glue function ...

X-Point Effect on Plasma Blob Dynamics

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Fabio Avino

Plasma blob dynamics on the high-field side in the proximity of a magnetic field null (X point) is investigated in TORPEX. A significant acceleration of the blobs towards the X point is observed. Close to the X point the blobs break apart. The E x B drifts ...

American Physical Society2016

A new type of poleable dielectric elastomer is introduced herein. The elastomer contains polymer nanoparticles with frozen molecular dipoles, which can be oriented at elevated temperatures in an electric field via poling. The aim is to provide a soft mater ...

Spin processes and charge dynamics in organic light emitting diodes

Francesco Comandè

In this thesis work we explore spin dependent processes and charge dynamics in α-NPD/Alq₃ based LEDs. Studies on polymer light emitting diodes based on PFO, which are fabricated by us, are also reported. Our objective is to shed light on the fundamental me ...

Electromagnetic Fields of a Lightning Return Stroke in Presence of a Stratified Ground

Marcos Rubinstein, Abdenabi Mimouni

We present an analysis of the nearby electromagnetic fields generated by lightning discharges in the presence of a horizontally stratified, two-layer ground. To the best of our knowledge, this is the first time the effect of ground stratification on underg ...

AC Magnetoelectrical Susceptibility Study of Multiferroics

Abhisek Datta

Multiferroics are materials in which ferroelectric and magnetic e.g., ferromagnetic or antiferromagnetic orders co-exist. Some of these show the magnetoelectric effect which is the coupling between electric and magnetic degrees of freedom leading to induct ...

Dual-Color Electroluminescence from Dot-in-Bulk Nanocrystals

Christophe Marcel Georges Galland

The emission color from colloidal semiconductor nanocrystals (NCs) is usually tuned through control of particle size, while multicolor emission is obtained by mixing NCs of different sizes within an emissive layer. Here, we demonstrate that recently introd ...

Thermodynamics of a continuous medium with electric and magnetic dipoles

Jean-Philippe Ansermet, Sylvain Bréchet

The thermodynamics of an electrically charged, multicomponent fluid with spontaneous electric and magnetic dipoles is analysed in the presence of electromagnetic fields. Taking into account the chemical composition of the current densities and stress tenso ...
