对具有等离子体诱导透明效应的平面纳米棒天线材料的光学特性进行了数值研究。所设计的超材料是由两个平行的银纳米棒包围的银纳米棒二聚体天线构成的。两个平行纳米棒和中间纳米棒二聚体天线之间的相互作用导致传输频谱中只有一个PIT波段。此外，通过打破结构对称性可以实现双坑窗和慢光。多波段深坑效应为在多频率下操纵光速提供了极好的潜力。(C) 2016 Elsevier B.V.版权所有
We numerically investigated the optical properties of planar nanorod antennas metamaterial that exhibits plasmon-induced transparency (PIT) effect. The designed metamaterial is made of a silver nanorod dimer antenna surrounded by two parallel silver nanorods. The interaction between two parallel nanorods and middle nanorod dimer antenna leads to a single PIT band in the transmission spectrum. Moreover, the double PIT windows and slow light can be realized by breaking the structure symmetry. The multi-bands PIT effect offers an excellent potential to manipulate the light speed at multi-frequencies. (C) 2016 Elsevier B.V. All rights reserved.
