A ferrite composite circulator according to the present invention performs various circulator actions with ferrite composites in which resonant TM modes and relevant circulating modes are utilized in multiple. Circulator performances are categorized into broadband operation, frequency dividing operation, and others, from the viewpoint of multiple circulation frequency operation. These operations have a common basis on the finding of multiple circulation frequency operation which has been achieved with a ferrite-dielectric composite circulator. Three types of ferrite composites used are a ferrite-conductor composite, a ferrite-dielectric-conductor composite, and a ferrite-ferrite composite.
