$\mathbb{R}^3$中反常局域共振引起的准静态隐身

On quasi-static cloaking due to anomalous localized resonance in $\mathbb{R}^3$

Hongjie Li, Jingzhi Li, Hongyu Liu

摘要:

这项工作涉及的隐形由于反常局域共振(CALR)在准静态政权。我们将[2,10]中的相关二维研究扩展到三维环境。在三维情况下,对于[2,10]中考虑的等离子体配置,不发生CALR。我们给出了两种不同的结构,确保CALR的发生。隐身装置可以没有核心或具有任意形状的核心。如果有一个核心,那么它内部的介电分布可以是任意的。

英文摘要:

This work concerns the cloaking due to anomalous localized resonance (CALR) in the quasi-static regime. We extend the related two-dimensional studies in [2,10] to the three-dimensional setting. CALR is shown not to take place for the plasmonic configuration considered in [2,10] in the three-dimensional case. We give two different constructions which ensure the occurrence of CALR. There may be no core or an arbitrary shape core for the cloaking device. If there is a core, then the dielectric distribution inside it could be arbitrary.
