摘要

本文提出了利用半无限介质界面处的菲涅耳反射系数反演超材料有效阻抗的方法。推导涉及到模态展开式在两个半无限介质的主导模态上的投影。结果表明，通过适当选择投影，可以从基于散射的形式中推导出许多以前通过场平均技术得到的有效阻抗公式。

Effective impedance modeling of metamaterial structures

We present methods for retrieving the effective impedance of metamaterials from the Fresnel reflection coefficients at the interface between two semi-infinite media. The derivation involves the projection of modal expansions onto the dominant modes of the two semi-infinite media. It is shown that a number of effective impedance formulas, previously obtained by field averaging techniques, can also be derived from the scattering-based formalism, by an appropriate choice of projection.
