Abstract
In this paper efficient solution techniques are presented which allow a fast and memory economical analysis of complicated antenna structures (e.g. a portable mobile telephone) radiating in the close vicinity of biological bodies. The computation is based on the method of moments, which we combine with physical optics, a special Green’s function expansion for certain layered geometries, and the multiple multipole method. The three different hybrid techniques are discussed and an example is presented to illustrate the application.
Résumé
Cet article présente des procédés de résolution efficaces permettant une analyse rapide et peu coûteuse en mémoire de structures complexes à antennes (notamment de téléphones portables), rayonnant à proximité de corps biologiques. Les calculs sont bases sur la méthode des moments, à laquelle sont combinés les principes de I’optique physique, une extension de la fonction de Green, spéciale pour certaines géométries en couches, ou encore la méthode du multipole multiple. Ces trois procédes hybrides différents sont discuteś et l’application est illustrée à I’aide d’un exemple.
