Description:
Magnetically tunable microwave bandpass filter structure have been designed and prepared by filling the ferrite rods into the metallic slits. The electromagnetic wave cannot propagate through the metallic slits. By filling the ferrite rods into the metallic slits, an enhanced optical transmission is obtained, which can be ascribed to the ferromagnetic resonance of the ferrite rods. Both the experimental and the simulated results show the center frequency and bandwidth of the passband can be tuned by the applied magnetic field, which exhibits a magnetically tunable behavior. This approach opens a way for designing tunable microwave bandpass filters.
