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

The field of nonlinear optics continues to evolve and impact many fields and particularly has
promising applications in the biomedical field. Furthermore, a major application, all-optical …

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 …

We study experimentally nonlinear tunable magnetic metamaterials operating at microwave
frequencies. We fabricate the nonlinear metamaterial composed of double split-ring …

Controllable and dispersive magnetic permeability in the metamaterials (MMs) provides us
more freedom to harness the propagation of ultrashort electromagnetic pulses at will. Here …

We have investigated modulation instability (MI) in metamaterials (MM) with both cubic and
quintic nonlinearities, based on a model appropriate for pulse propagation in MM with cubic …

Considering the theory of electromagnetic waves from the Maxwell's equations, we
introduce a (3+ 1)-dimensionsal cubic-quintic complex Ginzburg-Landau equation …

We show that modulation instability may occur even in the normal group-velocity dispersion
regime, or in the case of no group-velocity dispersion in metamaterials with a nonlinear …

The nonlinear optical coupler with a negative-index metamaterial (NIM) channel is different
from a conventional one, mainly in that the former has an effective feedback mechanism due …

In this paper we carry out a theoretical investigation on the propagation of spatiotemporal
solitons (light bullets) in the nonlinear metamaterial waveguides. Our theoretical study is …
