A Study of Multi-Layer Spiral Inductors for Remote Powering of Implantable Sensors

Giovanni De Micheli, Sandro Carrara, Jacopo Olivo

An approach based on multi-layer spiral inductors to remotely power implantable sensors is investigated. As compared to single-layer inductors having the same area, multi-layer printed inductors enable a higher efficiency (up to 35% higher) and voltage gai ...

3D Residual Eddy Current Field Characterisation: applied to Diffusion Weighted Magnetic Resonance Imaging

Rolf Gruetter, Alessandro Daducci, Gunnar Krüger, Kieran O'Brien, François Lazeyras

Clinical use of the Stejskal-Tanner diffusion weighted images is hampered by the geometric distortions that result from the large residual 3D eddy current field induced. In this work we aimed to predict, using linear response theory, the residual 3D eddy c ...

Local Excitation of Magnetostatic Modes in YIG

Jean-Philippe Ansermet, Elisa Papa

Described are ferromagnetic resonance (FMR) studies of the long wavelength magnetostatic wave modes of a single crystal yttrium iron garnet (YIG) slab magnetized by an in-plane field. A resonant circuit comprising a coil, 50 m in diameter, is used to excit ...

Development and validation of a tokamak skin effect transformer model

Stefano Coda, Jean-Marc Moret, Federico Alberto Alfredo Felici

A lumped parameter, state space model for a tokamak transformer including the slow flux penetration in the plasma (skin effect transformer model) is presented. The model does not require detailed or explicit information about plasma profiles or geometry. I ...

Magnetic Field Induced Redistribution of Exciton-Polariton Density on Confined Modes

Benoît Marie Joseph Deveaud, François Morier-Genoud, Gaël Nardin, Barbara Pietka

The influence of magnetic field on confined exciton-polariton modes inside a semiconductor microcavity is discussed. The three-dimensional confinement for exciton-polaritons is achieved by the mesa structures confining the photonic part of polaritons. We o ...

Modeling of Inductive Contactless Energy Transfer Systems

Pascal Meyer

In the domain of electronic devices and especially desktop peripherals, there is an industrial trend which consists in removing the cables that pollute our domestic and professional environments. In this sense, wireless communication protocols are already ...

Helium Flow and Temperature Distribution in a Heated Dual-Channel CICC Sample for ITER

Pierluigi Bruzzone

A spare, 3.5 m long dual-channel cable-in-conduit conductor (CICC) section, made according to the most recent ITER toroidal-field coil design, allowed conducting dedicated thermo-hydraulic experiments in the SULTAN test facility. The sample was heated by e ...
