用于紫外光磁超材料的混合金属-介质环形谐振器

Hybrid metal-dielectric ring resonators for optical magnetic metamaterials down to ultraviolet range

Jianwei Tang, Sailing He

摘要:

本文从麦克斯韦方程组出发,导出了开口环谐振器的磁共振模型。使用这个模型,我们重新审视开口环谐振器的缩放。受我们模型的启发,我们提出了一种新型的分裂混合金属-介质环形谐振器,其环形由中等高折射率的介质材料(如SiC,TiO 2,ZnS)(主要部分)组成,而金属(如Ag)填充间隙。这种新的磁性超材料能够克服开口环谐振器的饱和问题,因此能够在短波长下工作到紫外线范围。

英文摘要:

In this paper, we derive a model from Maxwell equations for the magnetic resonance of split-ring resonators. Using this model we revisit the scaling of split-ring resonators. Inspired by our model, we propose a new type of split-hybrid metal-dielectric ring resonator, of which the ring is made composed of moderately high index dielectric material (e.g. SiC, TiO2, ZnS) (for the major portion), while and metal (e.g. Ag) fills the gap. Such a new magnetic metamaterial is able to overcome the saturation problem of split-ring resonatorssaturation-free and therefore is able to operate at short wavelength down to ultraviolet range.
