Abstract

An attempt is made to answer the question posed in the title. Periodic metamaterials, namely, cubic photonic crystals with dielectric inclusions (including those with metallic properties), methods for introducing material equations (homogenization), and the possibility of describing metamaterials by scalar permeability and permittivity (or two scalar parameters) including negative values of their real parts, are considered. For photonic crystals, the Landau conclusion about the absence of high-frequency (optical) magnetic properties is confirmed. In particular, negative values of magnetic permeability or any of its components are impossible. Configurations of metamaterials with almost isotropic properties are presented without regard for spatial dispersion.

能存在各向同性负介电常数ε和磁导率μ超材料吗?

摘要

试图回答标题中提出的问题。周期性超材料,即具有介电夹杂物的立方光子晶体(包括具有金属性质的立方光子晶体),引入材料方程式(均质化)的方法,以及通过标量磁导率和介电常数(或两个标量参数)描述超材料的可能性,包括标称磁导率和负介电常数实部,被考虑。对于光子晶体,Landau关于不存在高频(光学)磁性的结论得到了证实。特别地,磁导率或其任何成分的负值是不可能的。提出了具有几乎各向同性特性的超材料的构型,而不考虑空间色散。
