A new invisibility cloak was recently proposed for hiding objects in front of a highly reflecting mirror. This cloak requires only modest values of optical constants with minimal anisotropy and thus can be implemented by using non-resonant dielectric materials, making it an ideal system for optical frequency operation. We implemented the cloak using an array of silicon nanorods fabricated by electron-beam lithography. We then directly visualized the cloaking effect by monitoring the light propagation inside the device using the near-field optical microscopy.
最近提出了一种新的隐形斗篷，用于在高反射镜前隐藏物体。这种斗篷只需要适度的光学常数，各向异性最小，因此可以通过使用非共振介电材料来实现，使其成为光学频率操作的理想系统。我们使用电子束光刻制造的硅纳米棒阵列实现了这种斗篷。然后，我们使用近场光学显微镜监测装置内部的光传播，直接观察到了隐形效果。
