ABSTRACT:
An electric power transmission system for hyperfrequencies having a gyromagnetic effect. The system includes a gyrator device having at least one disc-shaped wafer of gyromagnetic material such as ferrite, one side of which is set to a reference potential, and at least two tuning networks each comprising an inductance arranged on the other side of the wafer and one end of which is connected to the ground of the gyrator device whereas the other end is connected to an input terminal of the transmission system. The gyrator device is subjected to a homogeneous magnetostatic field for energizing the gyrator device and a layer of electrically insulating material of low permittivity is provided between the inductances and the wafer of gyromagnetic material. The device is usable for circulators, isolators or filters.
