Title
(EN) ELECTROMAGNETIC WAVE TRANSMISSION REDUCING MATERIAL
(FR) MATÉRIAU RÉDUISANT LA TRANSMISSION D'ONDES ÉLECTROMAGNÉTIQUES
Abstract
(EN)
The present invention relates to an electromagnetic millimetre wave transmission reducing material, preferably having a volume resistivity of more than 1 Ωcm, containing particles of at least an electrically conductive, magnetic or dielectric material and an electrically non-conductive polymer, wherein the transmission reducing material is capable of reducing transmission of electromagnetic waves in a frequency region of 60 GHz or more. The invention also relates to its use and method for reducing transmission as well as an electronic device comprising said transmission reducing material.
(FR)
La présente invention concerne un matériau réduisant la transmission d'ondes millimétriques électromagnétiques, ayant de préférence une résistivité volumique supérieure à 1 Ωcm, contenant des particules d'au moins un matériau électriquement conducteur, magnétique ou diélectrique et un polymère électriquement non conducteur, le matériau réduisant la transmission étant apte à réduire la transmission d'ondes électromagnétiques dans une région de fréquence égale ou supérieure à 60 GHz. L'invention concerne également son utilisation et un procédé de réduction de la transmission ainsi qu'un dispositif électronique comprenant ledit matériau réduisant la transmission.
