We demonstrate a new class of "coherent" metamaterials, where narrow band EIT-like transmission/reflection resonances correspond to a truly collective response of the entire ordered metamaterial array. The resonances appear as a result of coherent excitations of strongly interacting ordered meta-molecules and are controlled by the size of the array. Coherent maetamaterials provide a promising platform for various intriguing applications including slow-light and polarization controlling devices and the "lasing spaser", which we illustrate in a number of microwave, THz and optical experiments. Also, for the first time we experimentally show that resonant properties and losses in a photonic version of the metamaterial can be controlled through optical gain medium. (from session titled: Metamaterials - from modelling and fabrication to application).

We aim to explore electromagnetic metamaterials as a platform for mimicking and modelling a broader physical realm. Keystone physics ideas and phenomena of quantum physics such as Electromagnetically Induced Transparency, Bose-Einstein Condensation, lasing, the Mossbauer Effect, the Meissner Effect, parity violation in atoms and the concept of anion are among those that could be intriguingly close mimicked in classical electromagnetic meta-materials.

We introduce a new class of coherent metamaterials where regular ensembles of meta-molecules show collective, coherent narrow-band response leading to unusual electromagnetic properties that invites drawing the parallels with some well-know physical phenomena.
