Abstract
Electromagnetic modelling has become essential in the assessment of human exposure to radiowaves. The ever growing widespread use of wireless technologies around human bodies brings new studies for compliance analyses or exposure systems designs for biomedical researches. Numerical techniques have to be adapted to derive efficient models to tackle the complexity of phenomena. Recent developments are presented on the interactions with terminals or base station antennas: comparison of absorption between child and adult heads, source body coupling, accurate antenna modelling.


Résumé
La modélisation électromagnétique est devenue indispensable dans l'évaluation des interactions des ondes radiofréquences avec les personnes. L'utilisation de plus en plus intensive et proche des personnes des technologies sans fil ouvre une grande variété de situations à analyser dans les études de conformité ou d'élaboration de systèmes d'exposition destinés aux études biomédicales. Pour cela, les modèles et leurs utilisations doivent être adaptés pour gérer la complexité des phénomènes. Nous présentons dans ce papier quelques développements récents répondant à des problématiques actuelles aussi bien en ce qui concerne les terminaux que les antennes des stations de base : comparaison de l'exposition des enfants par rapport aux adultes, analyse du couplage source corps humain, développement de modèles d'antennes précis.


Key words: electromagnetic modelling, FDTD, human exposure, Specific Absorption Rate (SAR)

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
