Open the CIPO recordAbstract From the Canadian patent
A phase shifter suitable for operation at very high high-frequency power is composed of a waveguide in which ferromagnetic material is distributed along at least one plane extending in the direction of wave propagation. The ferromagnetic material is exposed to a static magnetic field oriented parallel to the plane. The ferromagnetic material is shaped so that it forms a plurality of three-dimensional regions which extend in the direction of the applied static magnetic field from one waveguide wall to the opposite waveguide wall. These regions may be provided by a plurality of ferromagnetic rods, preferably housed in one or more dielectric containers to direct a flow of coolant fluid or, by …
