论文摘要
在这里，我们介绍了第一原理的统一化理论。结果表明，在相当通用的环境中，可以正式引入有效参数，以描述使用有效的培养基形式主义的电磁场的宏观（在空间中缓慢变化）的时间演变。该理论应用于不同类型的“线材料”，其特征在于长波长极限中的强空间分散。有人强调的是，空间分散可能会以独特的方式量身定制，导致异国情调的隧道效应和宽带无损异常分散体中的波动现象。
Here, we present an overview of a first principles homogenization theory of periodic metamaterials. It is shown that in a rather general context it is possible to formally introduce effective parameters that describe the time evolution of macroscopic (slowly-varying in space) initial states of the electromagnetic field using an effective medium formalism. The theory is applied to different types of "wire metamaterials" characterized by a strong spatial dispersion in the long wavelength limit. It is highlighted that the spatial dispersion may tailor in unique ways the wave phenomena in wire metamaterials leading to exotic tunneling effects and broadband lossless anomalous dispersion.
