利用聚焦离子束写入的快速成型能力，制备了具有近红外磁共振的分裂环谐振器。通过改变设计参数，显示了从简并米氏共振到磁偶极子响应的连续过渡（见图）。特别是，在2.4 μ m波长处的负磁导率和在1.7 μ m波长处的负磁化率被证明。
Split-ring resonators with a magnetic resonance in the near-infrared have been fabricated using the rapid-prototyping capabilities of focused-ion-beam writing. By varying the design parameters, a continuous transition from a degenerate Mie resonance to a magnetic-dipole response is shown (see Figure). In particular, a negative magnetic permeability at a wavelength of 2.4 mu m and a negative magnetic susceptibility at a wavelength of 1.7 mu m are demonstrated.
