Surface-bound modes in metamaterials forged by drilling periodic hole arrays in perfect-conductor surfaces are investigated by means of both analytical techniques and rigorous numerical solution of Maxwell's equations. It is shown that these metamaterials cannot be described in general by local, frequency-dependent permitivities and permeabilities for small periods compared to the wavelength, except in certain limiting cases that are discussed in detail. New related metamaterials are shown to exhibit exciting optical properties that are elucidated in the light of our simple analytical approach.
通过解析技术和麦克斯韦方程组的严格数值解，研究了在理想导体表面钻出周期性孔阵列所形成的超材料中的表面束缚模式。结果表明，与波长相比，对于小周期情况，这些超材料一般不能用局部的、频率相关的介电常数和磁导率来描述，除了某些详细讨论的极限情况。根据我们简单的解析方法，新的相关超材料展现出令人兴奋的光学特性。
