Abstract

Bande absorbante de fuites pour joint de four micro-onde, installée dans et remplissant au moins partiellement un trajet de fuite, consistant en un matériau composite magnétique absorbant, où le matériau composite consiste en une poudre de ferrite ou un mélange de poudres de ferrites appropriés, dans une matrice organique (telle qu'un plastique, caoutchouc, polymère), ce (ou ces) ferrite(s) ayant la formule générale MO Fe203, où M est un métal bivalent tel que le Fe Mn, Ni, Cu, Mz, et où ce (ou ces) ferrite(s) représente(nt) un pourcentage total en poids dans le mélange, entre 80 et 95%, et où ce matériau composite ne représente pas d'effet de résonance, c'est-à-dire que son facteur de surtension Q est substantiellement égal ou inférieur à l'unité dans une gamme de fréquences égales ou supérieures à 2,45 GHz et de préférence entre 2,45 et 12 GHz.
