论文摘要
维塞拉戈（Veselago）的有远见的工作激发了过去十年中的深入研究工作，以实现具有前所未有的电磁特性的人造结构。这些结构被称为超材料，通常是基于金属的周期性共振结构，这些结构表明了自然物质可能性超出了有效的本构参数。例如，它们可以表现出光学磁性或同时有效的渗透率和介电常数，这意味着存在负折射率。然而，周期性的介电和极性材料（称为光子晶体）也可以表现出自然材料以外的EM功能。本文回顾了光子晶体系统超材料能力的条件和表现。
The visionary work of Veselago had inspired intensive research efforts over the last decade, towards the realization of man-made structures with unprecedented electromagnetic (EM) properties. These structures, known as metamaterials, are typically periodic metallic-based resonant structures demonstrating effective constitutive parameters beyond the possibilities of natural material. For example they can exhibit optical magnetism or simultaneously negative effective permeability and permittivity which implies the existence of a negative refractive index. However, also periodic dielectric and polar material, known as photonic crystals, can exhibit EM capabilities beyond natural materials. This paper reviews the conditions and manifestations of metamaterial capabilities of photonic crystal systems.
