Metamaterials enter the physics playground: from EIT to lasing spaser
We will overview our recent and ongoing research of a novel class of metamaterials exhibiting narrow high-Q transmission and reflection resonances linked to so-called "trapped-modes" excitations, and will introduce a concept of a "coherent" metamaterial, where narrow resonance is formed by a collective response of the entire metamaterial structure rather than by that of individual meta-molecules. Some remarkable parallels between the well established quantum effects and classical electromagnetic response of metamaterials will be explored. Cornerstone quantum phenomena such as the Mossbauer Effect, Einstein-Bose condensation and Electromagnetically Induced Transparency (EIT) are among those that can be mimicked through electromagnetic response of coherent "trapped-mode" metamaterials. Several intriguing applications of this new class of artificial media will be discussed, in particular achieving considerable delays in propagation of electromagnetic pulses, enhancing asymmetric transmission and building a coherent source of electromagnetic radiation fuelled by plasmonic oscillations - the lasing spaser.

Abstract
We will overview our recent and ongoing research of a novel class of metamaterials exhibiting narrow high-Q transmission and reflection resonances linked to so-called "trapped-modes" excitations, and will introduce a concept of a "coherent" metamaterial, where narrow resonance is formed by a collective response of the entire metamaterial structure rather than by that of individual meta-molecules. Some remarkable parallels between the well established quantum effects and classical electromagnetic response of metamaterials will be explored. Cornerstone quantum phenomena such as the Mossbauer Effect, Einstein-Bose condensation and Electromagnetically Induced Transparency (EIT) are among those that can be mimicked through electromagnetic response of coherent "trapped-mode" metamaterials. Several intriguing applications of this new class of artificial media will be discussed, in particular achieving considerable delays in propagation of electromagnetic pulses, enhancing asymmetric transmission and building a coherent source of electromagnetic radiation fuelled by plasmonic oscillations - the lasing spaser.
