Résumé des résultats (Abstract)

The project aims to develop the experience necessary for the practical exploitation of existing electromagnetic (EM) modelling tools and techniques in automotive applications such as EMC and vehicle antenna engineering. Although considerable research activity has been focused on the enabling technology that is required to support practical vehicle-scale EM modelling, relatively little research has been devoted to the practical modelling of large scale systems. Thus, many practical modelling questions remain un-answered, with the result that electromagnetic modelling has not yet been widely adopted in industry.
The primary output of the project will be guidelines for the practical application of EM modelling in the automotive industry, based on the processes and methodology developed by the partners in the course of the project. The GEMCAR Guidelines will address:
· possible application areas (eg. in design, specification, certification, standards);
· relevant electromagnetic issues (eg. immunity, emissions, intra-system EMC, antennas);
· efficient strategies for generating and exploiting simulation results;
· how best to use different techniques in order to develop practical industrial solutions.
Although the project is focused on automotive applications, the guidelines will nonetheless be equally applicable in all other transport sectors (rail, aerospace and marine) and will be of value in other industries where the EMC characteristics of large systems must be considered.
Work completed to date includes an analysis of potential user requirements, an investigation of approaches to maximise the efficiency of vehicle simulations, and measurement and simulation activity aimed at developing validation data for vehicle models. The latter is based on a range of numerical modelling techniques and different test environments, and demonstrates that good agreement can be achieved between models, and between models and measurements at realistic levels of complexity.
Dissemination of the project objectives and results has been via personal contacts, the project website (http://www.gemcar.org), and various contributions presented at international meetings and conferences and submitted to scientific journals:
· a paper presented at the Applied Computational Electromagnetics Society's 'Annual Review of Progress in Computational Electromagnetics' - USA, March 2002 (from EPFL);
· two papers presented at 'Colloque International sur la Compatibilité Electromagnétique' - Grenoble, March 2002 (one from EPFL, and one from EPFL, ONERA, EADS and MIRA jointly);
· a paper for AMEREM (a high power electromagnetics event) - USA, June 2002 (ONERA)
· three papers for the 5th European EMC Conference - Sorrento, September 2002 (from EADS, EPFL and MIRA).
A paper outlining the parallel NEC developed by EPFL is also submitted to the journal 'IEEE Transactions on EMC', while a website to support the implementation of this code is also being developed. A project workshop has also been proposed as part of the programme for EMC Zurich 2003, and it is expected that further papers based on GEMCAR will also be submitted for this key European conference.
Copies of these papers and presentations are available from the project website.
