Plasmon-induced transparency in metamaterials

Phys Rev Lett. 2008 Jul 25;101(4):047401. doi: 10.1103/PhysRevLett.101.047401. Epub 2008 Jul 23.


A plasmonic "molecule" consisting of a radiative element coupled with a subradiant (dark) element is theoretically investigated. The plasmonic molecule shows electromagnetic response that closely resembles the electromagnetically induced transparency in an atomic system. Because of its subwavelength dimension, this electromagnetically induced transparency-like molecule can be used as a building block to construct a "slow light" plasmonic metamaterial.
