Localization of Electromagnetic Fields in Disordered Fano Metamaterials
arXiv:1202.0088 · doi:10.1103/PhysRevB.85.121104
Abstract
We present the first study of disorder in planar metamaterials consisting of strongly interacting metamolecules, where coupled electric dipole and magnetic dipole modes give rise to a Fano-type resonant response and show that positional disorder leads to light localization inherently linked to collective magnetic dipole excitations. We demonstrate that the magnetic excitation persists in disordered arrays and results in the formation of "magnetic hot-spots".
