Abstract
In this paper we suggest and study a design solution of metamaterial made of raspberry-like clusters of silver triangular nanoprisms. We show that this design theoretically allows one to obtain isotropic negative effective permeability in the visible range even taking into account real dissipative losses in silver. To estimate the magnetic response of the structure two independent methods are used. The study is presented in view of prospective for isotropic doubly-negative metamaterials operating in the visible range.
等离子体三角形纳米棱镜簇在可见光范围内产生的各向同性负有效磁导率
摘要本文提出并研究了一种由覆盆子状银三角形纳米棱镜簇构成的超材料的设计方案。我们表明，这种设计在理论上允许人们在可见光范围内获得各向同性负有效磁导率，即使考虑到银的实际耗散损耗。为了估计结构的磁响应，采用了两种独立的方法。展望了在可见光范围内工作的各向同性双负超材料的前景。
