共焦椭圆等离子体激元结构中的反常局域共振引起的隐身
Cloaking due to anomalous localized resonance in plasmonic structures of confocal ellipses
摘要：
如果电介质材料的芯被具有非零损耗参数的负电介质材料的等离子体结构涂覆，则当损耗参数趋于零时可能发生异常局部共振，并且结构外部的源可能被掩盖。证明了同心圆结构存在反常局域共振（CALR）掩蔽，并计算了源被掩蔽的临界半径。本文证明了共焦椭圆结构发生CALR，并计算了临界椭圆半径。本文的方法使用与两个界面（核和壳的边界）相关联的Neumann-Poincaré型算子的谱分析。
英文摘要：
If a core of dielectric material is coated by a plasmonic structure of negative dielectric material with non-zero loss parameter, then anomalous localized resonance may occur as the loss parameter tends to zero and the source outside the structure can be cloaked. It has been proved that the cloaking due to anomalous localized resonance (CALR) takes place for structures of concentric disks and the critical radius inside which the sources are cloaked has been computed. In this paper, it is proved that CALR takes place for structures of confocal ellipses and the critical elliptic radii are computed. The method of this paper uses the spectral analysis of the Neumann-Poincaré type operator associated with two interfaces (the boundaries of the core and the shell).
