恢复超材料本构参数的物理意义
Restoring the Physical Meaning of Metamaterial Constitutive Parameters
摘要：
超材料均匀化通常基于受自然材料模型启发的隐含假设。然而，检索到的有效介电常数和磁导率，往往是非物理的，特别是在阵列谐振附近，最感兴趣的超材料应用。我们在这里解释典型的均匀化文物的性质，将它们与沿超材料阵列的有限相速度相关的磁电耦合的固有形式。我们的研究结果允许恢复适当的定义和物理意义的局部本构参数的超材料。
英文摘要：
Metamaterial homogenization is often based on implicit assumptions inspired to natural material models. Retrieved effective permittivity and permeability, however, are often non-physical, especially near the array resonances, of most interest for metamaterial applications. We explain here the nature of typical homogenization artifacts, relating them to an inherent form of magneto-electric coupling associated with the finite phase velocity along metamaterial arrays. Our findings allow restoring the proper definition and physical meaning of local constitutive parameters for metamaterials.
