本文给出了一种紧凑的局部带通滤波器的结果。我们使用两种不同的铁磁材料，Fe和NiFe，在微带结构中制作了该滤波器。这两个铁磁体的饱和磁化强度的不同值导致了不同的回旋磁共振频率，并在它们之间提供了一个局部带通区。结果表明，通过调节偏置磁场的大小，可以在很大范围内调谐滤波器的中心频率。在整个调谐频率范围(6-26 GHz)内，该滤波器的带宽几乎是恒定的(3.5±0.5 GHz)。理论计算与实验结果吻合较好。
This paper presents results for a compact, local bandpass filter. We fabricated the filter using two different ferromagnetic materials, Fe and NiFe, in a microstrip geometry. The different values of saturation magnetization of the two ferromagnets give rise to different gyromagnetic resonance frequencies and provide a local bandpass region between them. The results show that the center frequency of the filter can be tuned over a wide range by adjusting the magnitude of the bias magnetic field. The filter’s bandwidth is almost constant (3.5±0.5GHz) over the entire tuning frequency range (6–26GHz). Theoretical calculations are in good agreement with the experimental results.
