异向介质有效参数提取的频域差分法
Finite-difference frequency-domain method for the extraction of effective parameters of metamaterials
摘要：
在这里，我们报告了最近在[M]中提出的非局部均匀化方法的数值实现。Silveirinha，Phys.Rev.B75，115104（2007）]，使用有限差分频域方法来离散麦克斯韦方程。我们应用开发的形式主义来表征由电介质和金属颗粒形成的几种结构材料的非局部介电函数，特别是，我们提取局部介电常数，磁导率和磁电耦合参数时，这些是有意义的。结果表明，有限差分频域实现的均匀化方法是稳定和强大的，产生非常准确的结果。
英文摘要：
Here, we report a numerical implementation of the nonlocal homogenization approach recently proposed in [M. Silveirinha, Phys. Rev. B 75, 115104 (2007)], using the finite difference frequency-domain method to discretize the Maxwell-Equations. We apply the developed formalism to characterize the nonlocal dielectric function of several structured materials formed by dielectric and metallic particles, and in particular, we extract the local permittivity, permeability and magnetoelectric coupling parameters when these are meaningful. It is shown that the finite differences frequency domain implementation of the homogenization method is stable and robust, yielding very accurate results.
