In this paper, we derive the material parameter formulae for designing an electromagnetic invisibility anti-cloak of two-dimensional arbitrary geometry, which is conformal with the cloaked object. Different shapes of electromagnetic invisibility anti-cloaks are proposed to verify the correctness and effectiveness of the proposed formulae. The simulation results show that the invisibility anti-cloak can break cloak shielding and make the external electromagnetic waves into the cloak. This is not only to realize the transfer of information, but will not affect the role of cloak of stealth.
在本文中,我们推导了用于设计与被 cloaked 对象共形的二维任意几何形状电磁隐身反 cloak 的材料参数公式。提出了不同形状的电磁隐身反 cloak 以验证所提公式的正确性和有效性。仿真结果表明,隐身反 cloak 能够打破 cloak 的屏蔽作用,使外部电磁波进入 cloak 内部。这不仅能实现信息传递,而且不会影响 cloak 的隐身功能。
