The concept of invisibility in general has been imagined in science-fiction in fascinating ways such as invisible aircrafts, invisible cars, cape of invisibility etc. which has inspired a lot of interest in the field. The first crude attempt at achieving invisibility was inspired from ... En savoir plus

INTRODUCTION The coupling of the Schrödinger and Maxwell equations allows to predict the self-generated electromagnetic (EM) field for a quantum charged particle moving in a domain. Such problem is really challenging, and it must be investigated in order to simulate the behavior of a ... En savoir plus

For more than thirty years the GeePs Laboratory has been working on the numerical simulation of electromagnetic systems through numerous research topics. During this conference, we propose to present a recent problem that has been addressed by the laboratory. It is connected to ... En savoir plus

Background: Magnetic Induction Tomography (MIT) is an electromagnetic imaging technique that maps a material's electrical conductivity by inducing eddy currents via a primary oscillating magnetic field. The resulting secondary magnetic fields from the eddy currents are measured for image ... En savoir plus

As post-LHC particle accelerators of higher energy become prohibitively expensive, physisicists are turning to precision low-energy measurements of fundamental symmetries as an avenue for the discovery of new physics. A common requirement of many of these experiments is precision ... En savoir plus

COMSOL has been used to model the propagation of electromagnetic waves in fusion plasmas. For the first time, a finite element method has been used to solve the wave propagation for realistic fusion plasma parameters in the lower hybrid and ion cyclotron frequency ranges. Moreover, for ... En savoir plus

The construction of a superconducting aircraft motor demonstrator is underway under ASuMED project. Magnetized stacks of commercial superconducting tapes will be applied in a rotor in place permanent magnets. The rotor will be cooled with liquid hydrogen down to approximately 20K to ...

We study cylindrical and spherical shell structures that have cloaking material properties proposed by Pendry et al. We use 2D and 3D time-harmonic analysis to study the field distribution and power flow for various arrangements of these structures. We have shown that the COMSOL RF ... En savoir plus

This paper describes the automatic optimization of an electromagnetic actuator using a genetic algorithm.  The actuator modeled here is dedicated for charge changing valve actuation in internal combustion engines. In the first step of the simulation, several operating points are ... En savoir plus

As part of the European Research Roadmap to the Realization of Fusion Energy [1], the Divertor Tokamak Test facility (DTT) [2] aims to study alternative divertor configurations in view of the EU-DEMO [3] power exhaust handling issues. The DTT superconducting magnet system comprises 18 ... En savoir plus
