介绍了一类微波光子带隙材料的实验研究，其中磁导率μ在材料内部呈周期性变化。这种材料是使用磁性纳米线阵列的周期性排列来制造的。对于介质或金属PBG，禁带行为随固定磁结构空间周期性的几何参数而变化。磁光子带隙是由带隙附近的铁磁共振效应引起的。
We present an experimental investigation of a class of microwave photonic band-gap (PBG) materials, in which the magnetic permeability μ varies periodically within the material. This material is fabricated using a periodic arrangement of arrays of magnetic nanowires. As for dielectric or metallic PBG, the band-gap behavior varies with the geometrical parameters fixing the spatial periodicity of the magnetic structure. The magnetic photonic band gap is induced by the presence of a ferromagnetic resonance effect in the vicinity of the band gap.
