Title
(EN) GRAPHENE-COATED COUPLING COIL FOR AC RESISTANCE REDUCTION
(FR) BOBINE DE COUPLAGE REVÊTUE DE GRAPHÈNE POUR RÉDUCTION DE RÉSISTANCE À COURANT ALTERNATIF
Abstract
(EN)
At least one graphene layer is formed to laterally surround a tube so that the basal plane of each graphene layer is tangential to the local surface of the tube on which the graphene layer is formed. An electrically conductive path is provided around the tube for providing high conductivity electrical path provided by the basal plane of each graphene layer. The high conductivity path can be employed for high frequency applications such as coupling coils for wireless power transmission to overcome skin depth effects and proximity effects prevalent in high frequency alternating current paths.
(FR)
La présente invention concerne au moins une couche de graphène formée de façon à entourer latéralement un tube de manière à ce que le plan de base de chaque couche de graphène soit tangent à la surface locale du tube sur lequel est formée la couche de graphène. Un chemin électroconducteur est prévu autour du tube pour fournir un chemin électrique à conductivité élevée prévu par le plan de base de chaque couche de graphène. Le chemin à conductivité élevée peut être employé pour des applications de hautes fréquences telles que des bobines de couplage pour transmission d'énergie sans fil afin de surmonter les effets de profondeur de pénétration et les effets de proximité présents sur les chemins de courant alternatif à haute fréquence.
