A ferromagnetic film, which has an inherent resonant frequency, is disposed in a cavity resonator. An electromagnetic wave, which has an input frequency equal to the resonant frequency of the ferromagnetic film, is introduced to the ferromagnetic film from an orifice of the cavity resonator to generate a ferromagnetic resonance in the ferromagnetic film, and thus, multiply the input frequency of the electromagnetic wave.
