fabricating metamaterials using the fiber drawing method

超材料是人造复合材料，制造组装远小于波长，他们在操作1。他们欠他们的电磁特性，而不是其成员的结构，组成它们的原子。例如，副波长的金属丝可以被布置为具有一个有效的电动的或正或负的介电常数是在一个给定的频率，在对比的金属本身2。这种前所未有的控制光的行为有可能导致一些新型设备，如隐形斗篷，负折射率材料4，和镜头，低于衍射极限的5解决对象。然而，光纤，中红外和太赫兹频率工作在传统的超材料采用纳米和微加工技术，价格昂贵，而且生产出样品，最多几个世纪尺寸6-7的 timetres中。在这里，我们提出了一种制造方法产生几百米的金属丝超材料的纤维形态，表现出太赫兹电浆反应8。我们结合堆栈和绘制技术用于生产微结构聚合物光纤9与泰勒线过程10，使用铟的聚甲基丙烯酸甲酯（PMMA）的管内导线。聚甲基丙烯酸甲酯的选择，因为它是一个简单的处理，提拉介质，适当的光学特性，在太赫区域;铟，因为它具有熔融温度为156.6℃，这是适当的codrawing与PMMA。我们包括铟丝直径为1mm的，纯度为99.99％的PMMA管与1毫米内径（ID）和12毫米的外径（OD）是在一端密封。该管被抽真空并提取的外直径为1.2毫米。将得到的纤维，然后切成小块，并堆叠成一个较大的PMMA管。此堆栈被密封在一端和送入炉中，而被迅速地绘制，减少的结构的直径的10倍，并通过100倍的增加长度。这种纤维具有功能的微型和纳米级的，本质上是灵活的，大规模生产的，可织表现出没有在自然界中发现的电磁性能。它们代表从太赫兹到光的频率，如无形的纤维，编织负折射率布，和超分辨镜头一些新型器件的一种很有前途的平台。

超材料纤维，使用所描述的技术生产。他们从一个预成型坯1毫米PMMA含有直径为100μm的连续的铟电线的纤维， 如图2中所示，这反过来又被从一个预成型体的1毫米的铟包含内有10毫米的聚合物护套的导线，这是产生绘制组装通过套管的适当大小的聚合物管，与图1的示意图中所示。电浆在THz范围内的响应一个超材料的纤维的一个例子的横截面的显微镜图像如图3?...
