We experimentally demonstrate a bendable cloaking structure composed of obliquely stacked planar metallic shells that individually enclose the objects to be hidden. The ensemble of shells acts as a disordered oblique grating capable of bending along a curved structure and exhibits broadband invisibility from 0.2 to 1.0 THz. Hiding cloaked objects sized hundreds of microns could prevent the detection of certain powders that are sensitive to terahertz waves; such a cloaking structure can also be considered as a shape-changing passageway that transfers the electromagnetic waves without interfering with them. Our approach provides a unique way to achieve broadband electromagnetic invisibility.

宽带太赫兹隐形的可弯曲的无序超材料。

我们通过实验证明了一种可弯曲的隐形结构，该结构由倾斜堆叠的平面金属壳组成，这些壳单独包围要隐藏的对象。贝壳的集合体起无序的倾斜光栅的作用，能够沿着弯曲的结构弯曲，并展现出0.2至1.0 THz的宽带不可见性。隐藏几百微米的隐蔽物体可能会阻止检测到某些对太赫兹波敏感的粉末。这样的隐身结构也可以被认为是在不干扰电磁波的情况下传递电磁波的变形通道。我们的方法提供了一种实现宽带电磁隐身的独特方法。
