隐身是人类自古以来的美妙幻想和愿望。近年来，随着人工微结构超构材料领域的不断发展，隐身具备了坚实的科学理论基础和实现条件。早期的隐身设计大多数是基于变换光学原理，科学家们利用超构材料实现了渐变的折射率并在多个频段实现了隐身现象。然而，变换光学隐身器件通常具有较大的尺寸且不易制备，这极大地限制了隐身器件的应用和发展。近年来，超表面作为超构材料的二维对应物，由于其轻薄特性、制备容易、以及强大的电磁波调控能力吸引了人们广泛的关注和研究兴趣。利用超表面实现的超薄隐身器件有望解除传统隐身器件对大尺寸和极端参数材料的依赖，进一步推动了隐身领域的发展，并使隐身器件迈向实际应用。文中对近年来基于超表面的超薄隐身器件的相关研究进行了简要的回顾，着重介绍了其隐身原理，实现方法以及优劣势，最后对领域发展前景和方向提出了一些建议。

Non-Hermitian characteristics accompany any photonic device incorporating spatial domains of gain and loss. In this work, a one-dimensional beam-forming array playing the role of the active part is disturbed from the scattering losses produced by an obstacle in its vicinity. It is found that the placement of the radiating elements leading to perfect beam shaping is practically not affected by the presence of that jammer. A trial-and-error inverse technique of identifying the features of the obstacle is presented based on the difference between the beam target pattern and the actual one. Such a difference is an analytic function of the position, size, and texture of the object, empowering the designer to find the feeding fields for the lasers giving a perfect beam forming. In this way, an optimal beam-shaping equilibrium is re-established by effectively cloaking the object and nullifying its jamming effect.
