We propose a feasible design for an annulus-based dielectric metamaterial cloak to not only reduce Ohmic losses from metallic metamaterials but also avoid manual misalignment when utilizing discrete dielectric metamaterials. The designed cloak is authenticated by the finite-integration method, and the corresponding field distributions without and with hidden objects are found to reveal the invisibility of the cloak. In addition, illusion optics are comprehended by comparing the field distributions of the dielectric-metamaterial-cloak-based illusion-device and an illusion object. With the abovementioned characteristics of the proposed cloak using an annulus-based dielectric metamaterial, in simulation, we successfully approach the features of the reciprocal cloak, which conceals multiple objects with vision and movement.

具有错觉光学特性的环空介电超材料披风的设计

我们提出了一种基于环空的电介质超材料披风的可行设计，不仅可以减少金属超材料的欧姆损耗，而且还可以避免在使用分立电介质超材料时的人工对准问题。通过有限积分方法对设计的隐身衣进行身份验证，发现没有隐身物体和隐身物体的相应场分布揭示了隐身衣的隐身性。另外，通过比较基于介电材料披风的幻觉装置和幻觉对象的场分布来理解幻觉光学。通过使用基于环空的介电超材料的拟议披风的上述特征，在仿真中，我们成功地实现了相互披风的功能，该功能可通过视觉和运动隐藏多个对象。
