Instantaneous radiation from time-varying electric and magnetic dipoles

Romain Christophe Rémy Fleury, Mohammad Sajjad Mirmoosa

Radiation from magnetic and electric dipole moments is a key subject in the theory of electrodynamics. Although people treat the problem thoroughly in the context of the frequency domain, the problem is still not well understood in the context of the time ...

Efficacy of pulsed electromagnetic fields and electromagnetic fields tuned to the ion cyclotron resonance frequency of Ca2+ on chondrogenic differentiation

Philippe Renaud, Harald Van Lintel, Hanie Kavand

Previous studies provide strong evidence for the therapeutic effect of electromagnetic fields (EMFs) on different tissues including cartilage. Diverse exposure parameters applied in scientific reports and the unknown interacting mechanism of EMF with biolo ...

Linear Parameter-Varying Kalman Filter for angular velocity estimation of a reaction sphere actuator for satellite attitude control

Alireza Karimi, Leopoldo Rossini, Guzmán Borque Gallego

This paper presents a novel angular velocity estimation strategy of a Reaction Sphere (RS) for satellite attitude control based on a Linear Parameter-Varying (LPV) Kalman Filter. The reaction sphere is a permanent magnet synchronous spherical actuator whos ...

Using pot-magnets to enable stable and scalable electromagnetic tactile displays

Herbert Shea, Juan José Zarate

We present the design, fabrication, characterization and psychophysical testing of a scalable haptic display based on electromagnetic (EM) actuators. The display consists of a 4x4 array of taxels, each of which can be in a raised or a lowered position, thu ...

Comprehensive analysis of Lenz effect on the artificial heart valves during magnetic resonance imaging

Juan Ramon Mosig, Laleh Golestanirad

This work presents results of a comprehensive analysis of the Lenz effect due to motion of artificial heart valves during magnetic resonance imaging. The interaction of rotating metallic heart valves with magnetic fields is studied by performing a time-dom ...

Effect of Model Accuracy on the Result of Computed Current Densities in the Simulation of Transcranical Magnetic Stimulation

Juan Ramon Mosig, Michael Mattes, Laleh Golestanirad

One of the most hindering limitations in the simulation of a realistic biological system is the complexity of the model which may easily lead to a very heavy computational burden. This may seriously question the possibility of optimizing system parameters ...

Structural analysis of the jet TAE antenna

Ambrogio Fasoli, Duccio Testa

In this paper the mechanical design of the new active MHD antennas for JET is described and the structural/mechanical analysis for the antennas is presented. These new antennas replace the existing n = 1 or 2 saddle coils with a set of eight smaller antenn ...

Modification of brushless DC motor back-EMF shape-application to noise reduction

Yves Perriard

The brushless DC motors are normally built with rotor mounted PMs, which create the necessary back EMF voltage to produce a mechanical power. The shape of this back-EMF voltage is very important compared to the phase voltage supply one. Indeed, the electro ...

Localized Eddy Current Compensation Using Quantitative Field Mapping

Rolf Gruetter

Eddy current effects induced by switched gradients in proximal conducting structures are traditionally reduced by applying preemphasis currents whose amplitudes and decay characteristics must be set to offset the eddy current fields. We present an expediti ...
