可以设计元表面来实现指定的功能。仔细的元原子设计和排列可以实现均匀和非均匀布局，从而实现特殊的操作入射波的能力。从本质上讲，散射波的控制在无线通信和隐身技术中至关重要。提供全面操作的低轮廓和轻质涂层非常适合伪装，欺骗传感，雷达认知控制和国防安全等应用。在这里，我们提出了一种不改变物体而实现电磁错觉的方法。提出了一维介质的原理证明并进行了实践。这个想法是设计环境而不是物体涂层。这项工作为多功能设计铺平了道路，将在智能环境的帮助下改善电磁安全应用。
Metasurfaces can be designed to achieve prescribed functionality. Careful meta-atom design and arrangement achieve homogeneous and inhomogeneous layouts that can enable exceptional capabilities to manipulate incident waves. Inherently, the control of scattering waves is crucial in wireless communications and stealth technologies. Low-profile and light-weight coatings that offer comprehensive manipulation are highly desirable for applications including camouflaging, deceptive sensing, radar cognition control, and defense security. Here, we propose a method that achieves electromagnetic illusion without altering the object. A proof of principle is proposed and practiced for one-dimensional media. The idea is to engineer the environment instead of the object coating. This work paves the way for versatile designs that will improve electromagnetic security applications with the aid of smart environments.
