Abstract

We describe a novel type of electromagnetic cloak designed to conceal an object in a corner, and demonstrate its excellent performance by employing direct numerical simulation. Furthermore, we study the angular dependence and the effect of loss on the invisibility performance and compare ideal and simplified cloaks. The proposed structure has homogeneous constitutive parameters, which greatly simplifies practical realization.

摘要

我们描述了一种新型电磁隐身衣，其设计目的是将角落中的物体隐藏起来，并通过直接数值模拟展示了其卓越性能。此外，我们研究了角度依赖性以及损耗对隐身性能的影响，并比较了理想隐身衣和简化隐身衣。所提出的结构具有均匀的本构参数，这极大地简化了实际实现过程。
