[Méthode quasi universelle pour mesurer les caractéristiques électromagnétiques de tous types de matériaux dans le domaine des hyperfréquences]
Aujourd'hui, connaître les valeurs expérimentales des caractéristiques électromagnétiques des différents matériaux devient incontournable avec l'avancée des communications sans fil. Les outils existants pour effectuer de telles caractérisations présentent des limites, soit en termes de bandes fréquentielles réduites, soit en termes de versatilité suivant les différents types de matériaux. Sur la base de procédures bien connues dans la communauté scientifique du domaine, nous présentons dans ce contexte une nouvelle cellule de mesure équipée d'un porte-échantillon pouvant confiner tous les types de matériaux : solides, semi-solides (matériaux granulaires ou pulvérulents), liquides. Cette technique permet aussi de caractériser des matériaux de faibles épaisseurs, qui sont aussi de plus en plus utilisés dans le domaine de la RFID ou des antennes sur substrats souples.
Knowing the electromagnetic characteristics of different materials has become a major topic with the growing of wireless communications. The actual tools to perform this characterization have some limits, either in terms of limited frequency band, or in terms of inconstancy according to the different kinds of materials. On the basis of well-known procedures in the microwave domain, we present a new measurement cell equipped with a sample holder that can contain any kind of materials: solids, semi-solids (granular or powder materials), liquids. This technique can also characterize materials of thin thickness that are also more and more used in the RFID domain or in the realization of antennas on flexible substrates.
