| 摘 要： | 超材料具有天然材料所不具备的特殊电磁特性。基于分形曲线的超材料因其展现出深度亚波长与多带特性,引起广泛关注。主要研究了Hilbert分形曲线在微波频段传播的电磁特性,并对各阶曲线透射谱频率以及共振电流分布特点进行了研究,发现Hilbert分形曲线结构总长度与共振频率的波长满足近似条件下的半波理论。同时,研究了曲线结构尺寸相对于基模共振波长的亚波长特征。

| Abstract: | Metamaterials have the typical electromagnetic characteristics that natural materials don＇t have. The space-filling curve based metamaterials have received much attention because of their intrinsic sub-wave length and multi-band characteristics. In this paper, we have mainly investigated the electromagnetic characteristics of Hilbert curves in microwave frequency domain. We have also studied the transmission spectrum frequency and resonance current distribution of the curves. The results show that a deeply sub-wave length magnetic resonance is supported by the fractal pattern, exhibiting the wavelength-to-size ratio more than 20. The sub-wave length electromagnetic properties of the Hilbert curve will be beneficial to realize high-performance metamaterials. |
