We study the anisotropic properties of multilayer fishnet optical metamaterials and describe topological transitions between the elliptic and hyperbolic dispersion regimes. In contrast to other hyperbolic media, multilayer fishnet metamaterials may have negative components not only in the effective permittivity tensor but also in the effective permeability tensor, thus allowing the realization of magnetic hyperbolic and generalized indefinite media.
我们研究了多层鱼网光学超材料的各向异性特性,并描述了椭圆和双曲线色散区域之间的拓扑转变。与其他双曲线介质不同,多层鱼网超材料不仅在有效介电常数张量中可能具有负分量,而且在有效磁导率张量中也可能具有负分量,从而实现磁双曲线和广义不定介质。
