幻觉媒体：使用可实现的超材料生成虚拟对象
Illusion Media: Generating Virtual Objects Using Realizable Metamaterials
摘要：
我们提出了一类光学变换媒体，错觉媒体，使封闭的对象不可见，并产生一个或多个虚拟对象的期望。我们应用所提出的媒体设计的微波设备，它转换成两个虚拟对象的实际对象。这样的错觉装置表现出不寻常的电磁行为，通过全波模拟验证。与已发表的由同时具有负介电常数和负磁导率的左手材料组成的错觉装置不同，所提出的错觉介质具有有限的正介电常数和正磁导率。因此，所设计的器件可以使用人造超材料来实现。
英文摘要：
We propose a class of optical transformation media, illusion media, which render the enclosed object invisible and generate one or more virtual objects as desired. We apply the proposed media to design a microwave device, which transforms an actual object into two virtual objects. Such an illusion device exhibits unusual electromagnetic behavior as verified by full-wave simulations. Different from the published illusion devices which are composed of left-handed materials with simultaneously negative permittivity and permeability, the proposed illusion media have finite and positive permittivity and permeability. Hence the designed device could be realizable using artificial metamaterials.
