论文摘要
我们通过实验显示了由转换光学(TO)技术设计的幻觉装置的结果。坐标转换将虚拟空间中的零厚度映射到物理空间中的有限区域,从而产生了称为光学无效介质(ONM)的极端材料特性。结果,放置在核心介质内部的对象将看起来更大,外部观察者。使用圆柱坐标中的金属二级分层结构实现ONM介质。还详细介绍了来自圆柱体对象的散射场的封闭式溶液,以分析性地证明幻觉效果。使用有效的培养基理论,使用径向结构的空气和铁皮实现ONM介质。我们通过实验性地制造ONM并使用ONM显示散射效果。为了实现幻觉验证,金属管已插入由有机玻璃制成的核心介质的中心,并被ONM包围。
We experimentally show the results of the illusion device designed by the transformation optics (TO) technique. The coordinate transformation maps a zero thickness in virtual space to a finite region in physical space, yielding extreme material properties called optical null media (ONM). As a result, an object placed inside the core media will look larger to an outside observer. ONM media is realized using metal-dielectric layered structures in cylindrical coordinates. Also closed-form solutions for the scattering field from a cylindrical object are given in detail to prove illusion effect analytically. ONM media is realized using air and iron sheets in radial structure using effective medium theory. We experimentally fabricate the ONM and show the scattering effect using the ONM. For achieving illusion validation, a metallic pipe has been inserted into the center of the core medium made of Plexiglas and surrounded by ONM.
