This Colloquium presents an overview of the research on nonlinear electromagnetic
metamaterials. The developed theoretical approaches and experimental designs are …

Metamaterials, ie artificial, man-made media designed to achieve properties not available in
natural materials, have been the focus of intense research during the last two decades …

We study theoretically the dramatic enhancement of spontaneous emission in metamaterials
with the hyperbolic dispersion modeled as a cubic lattice of anisotropic resonant dipoles. We …

A metamaterial (MM) differs from an ordinary optical material mainly in that it has a
dispersive magnetic permeability and offers greatly enhanced design freedom to alter the …

Spontaneous chiral symmetry breaking underpins a variety of areas such as subatomic
physics and biochemistry, and leads to an impressive range of fundamental phenomena …

Magnetic metamaterials composed of split-ring resonators or U-type elements may exhibit
discreteness effects in THz and optical frequencies due to weak coupling. We consider a …

We analyze the effect of microscopic disorder on the macroscopic properties of composite
metamaterials and study how weak statistically independent fluctuations of the parameters …

A rf superconducting quantum interference device (SQUID) array in an alternating magnetic
field is investigated with respect to its effective magnetic permeability, within the effective …

The existence and stability of discrete breathers (DBs) in one-and two-dimensional magnetic
metamaterials (MMs), which consist of periodic arrangements (arrays) of split-ring …

Magnetic metamaterials consist of small metallic resonators of the split ring type.
Microscopic properties of these structures are governed by near field coupling between …
