Composite resonator

A composite resonator comprising a composite made of a centrally disposed conductor puck and a ferrite layer disposed concentrically with and adjacent to said conductor puck, and an external magnetic field source for applying an external magnetic field of predetermined intensity to said composite so that at least two circulation modes perpendicular to said magnetic field can coexist, said ferrite layer being a multi-layer composite made of a plurality of directly contacting concentric layers having mutually different saturation magnetizations for utilizing at least one subsidiary circulation mode produced in said multi-layer composite.

A composite resonator comprising a ferrite composite made of at least three concentrically disposed ferrite layers, thin dielectric layers interposed between the respective layers of said ferrite composite to weaken electromagnetic coupling of adjacent ones of said ferrite layers, and an external magnetic field source for applying an external magnetic field of predetermined intensity to said composite.
