Abstract

Metamaterials are artificial media structured on the sub-wavelength scale. While conventional materials derive their electromagnetic characteristics from the properties of atoms and molecules - metamaterials enable us to design our own 'meta-molecules' and interactions between them and thus access new ground-breaking functionalities. <br/>Metamaterials are expected to have an impact across the entire range of technologies where electromagnetic radiation is used, and provide a flexible platform for modelling and mimicking fundamental physical effects as diverse as superconductivity and cosmology and for templating electromagnetic landscapes to facilitate observations of otherwise difficult to detect phenomena.<br/>We report an overview on our recent results on new phenomena in metamaterials underpinned by meta-molecular interactions. This will include results on light localization in metamaterial arrays, metamaterial "lasing spaser", quantum Purcell enhancement of luminescence and spectral mode collapse.<br/>Furthermore we will introduce a range of novel functionalities observed in nanostructured photonic metamaterials containing nonlinear and active media such as switchable chalcogenide glass, carbon nanotubes, graphene and semiconductor quantum dots.
