Slow waves on magnetic metamaterials and on chains of plasmonic nanoparticles: Driven solutions in the presence of retardation

Slow waves on resonant elements offer a unique tool for guiding electromagnetic radiation. This paper introduced a novel method for dispersion retrieval for finite metamaterial/plasmonic chains, relevant for practical applications, as opposed to existing methods for infinite structures. This work has led to a collaboration with the Max-Planck-Institute Erlangen, to a further eight publications, resulting in a €3m funding (School in Advanced Optical Technologies Erlangen SAOT) by the German Research Council (DFG). Our method, enabling design of metamaterials and plasmonic structures with desired properties was employed in tunable (Canberra U), active (QML), leaky-wave (Texas U) and silver-nanospheres metamaterials (NTU Singapore).
