- A split-ring resonator (SRR) is an artificially produced structure common to metamaterials. Its purpose is to produce the desired magnetic susceptibility (magnetic response) in various types of metamaterials up to 200 terahertz. These media create the necessary strong magnetic coupling to an applied electromagnetic field, not otherwise available in conventional materials. For example, an effect such as negative permeability is produced with a periodic array of split ring resonators. A single cell SRR has a pair of enclosed loops with splits in them at opposite ends. The loops are made of nonmagnetic metal like copper and have a small gap between them. The loops can be concentric or square, and gapped as needed. A magnetic flux penetrating the metal rings will induce rotating currents in the rings, which produce their own flux to enhance or oppose the incident field (depending on the SRR resonant properties). This field pattern is dipolar. The small gaps between the rings produces large capacitance values which lowers the resonating frequency. Hence the dimensions of the structure are small compared to the resonant wavelength. This results in low radiative losses and very high quality factors. (en)
- 开口谐振环,（split-ring resonator）是磁性超材料的一种。Pendry指出一对同心的亚波长大小的开口谐振环，互相反向放置,可以有效地提高磁导率1。事实上开口谐振环这一术语早在Pendry之前就被创建了。上个世纪80年代早期，Hardy用一种类似的结构和同样的术语描述了带有一条线状缺口的空心圆柱体在大约1GHz的频率上表现出来的2。Pendry和他的伙伴们把这种结构改造成现在这种形式，这种设计在当今的超材料研究中被用作许多超磁单元的原型。 (zh)
