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
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
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
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 ...

High precision ‘designer’ magnetic fields are needed for the latest generation of particle physics experiments, such as the search for the Electric Dipole Moment of the neutron. The shift in focus from the high energy frontier to precision measurements of these small quantities will ... En savoir plus
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
Electromagnetic Forming (EMF) is a promising and relatively new manufacturing technology having significant advantages over conventional forming processes. A primary characteristic of this process is use of noncontact electromagnetic forces to achieve forming and shaping of various ... En savoir plus
