反磁体：用超导体-超材料混合体控制磁场
Antimagnets: Controlling magnetic fields with superconductor-metamaterial hybrids
摘要：
从磁纪录到能量产生再到捕获冷原子，磁性在科学技术中非常重要。物理学家们已经成功地掌握了磁学--几乎随心所欲地创造和操纵磁场。令人惊讶的是，至少有一个属性到目前为止一直是难以捉摸的：如何“关闭”磁性材料与现有磁场的磁相互作用，而不修改它们。在这里，我们介绍了反磁体，一种设计，以隐藏从其外部的一个给定的体积的磁响应，而不改变外部磁场，在某种程度上类似于最近的理论建议，用超材料掩盖电磁波。然而，与这些需要极端材料特性的设备不同，我们的设备是可行的，只需要两种可用的材料：超导体和各向同性磁性材料。抗磁体可以应用于磁基医疗技术，如MRI或减少血管或平面的磁特征。
英文摘要：
Magnetism is very important in science and technology, from magnetic recording to energy generation to trapping cold atoms. Physicists have managed to master magnetism - to create and manipulate magnetic fields- almost at will. Surprisingly, there is at least one property which until now has been elusive: how to 'switch off' the magnetic interaction of a magnetic material with existing magnetic fields without modifying them. Here we introduce the antimagnet, a design to conceal the magnetic response of a given volume from its exterior, without altering the external magnetic fields, somehow analogous to the recent theoretical proposals for cloaking electromagnetic waves with metamaterials. However, different from these devices requiring extreme material properties, our device is feasible and needs only two kinds of available materials: superconductors and isotropic magnetic materials. Antimagnets may have applications in magnetic-based medical techniques such as MRI or in reducing the magnetic signature of vessels or planes.
