基于变换光学，我们提出了一种收缩装置，它可以根据需要将任意物体虚拟地变换为具有不同材料参数的小尺寸物体。这种错觉装置会迷惑探测器或观察者，因此无法感知封闭物体的真实尺寸和材料参数。我们利用超材料制造并测量了一种收缩器件，该器件工作在非谐振频率且损耗低。该装置已通过数值模拟和圆形和方形物体的实验得到验证。已表现出良好的收缩性能。
Based on transformation optics, we present a shrinking device, which can transform an arbitrary object virtually into a small-size object with different material parameters as one desires. Such an illusion device will confuse the detectors or the viewers, and hence the real size and material parameters of the enclosed object cannot be perceived. We fabricated and measured a shrinking device by using metamaterials, which works at the nonresonant frequency and has low loss. The device has been validated by both numerical simulations and experiments on circular and square objects. Good shrinking performance has been demonstrated.
