Abstract

L'invention se rapporte à la transmission sans pertes, à bas niveau de puissance, d'ondes électromagnétiques hyperfréquence dans un dispositif non réciproque. On utilise à cet effet des grenats polycristallins à très faible largeur de raie de résonance gyromagnétique, qui présentent de nombreux avantages sur les monocristaux magnétiques, en particulier la possibilité de choisir une composition qui s'adapte au cas d'utilisation, notamment aux fréquences comprises entre 1 GHz et 3,5 GHz L'invention s'applique à tous les dispositifs non réciproques et notamment aux circulateurs à jonction.
