虽然无界超材料的有效介质处理似乎已经得到了很好的建立和有力的证明，但有限结构中的相关现象还没有得到足够的关注。我们报告的介观效应与有限的离散超材料样品的边界，这可能会使有效的介质描述无效。我们展示了如何通过适当选择边界配置来避免这种影响。由于所有超材料的实现都是自然有限的，我们相信我们的发现对未来的超材料研究至关重要。(C)2012美国光学学会
While the effective medium treatment of unbounded metamaterials appears to be well established and firmly proven, related phenomena in finite structures have not received sufficient attention. We report on mesoscopic effects associated with the boundaries of finite discrete metamaterial samples, which can invalidate an effective medium description. We show how to avoid such effects by proper choice of boundary configuration. As all metamaterial implementations are naturally finite, we are confident that our findings are crucial for future metamaterial research. (C) 2012 Optical Society of America
