Title:  Travelling waves in PT-symmetric nonlinear metamaterials



Abstract: In this talk we will investigate a one-dimensional

parity-time (PT)-symmetric magnetic metamaterial consisting of

split-ring dimers having gain or loss. Employing a Melnikov analysis

we will talk about the existence of localized travelling waves, i.e.

homoclinic or heteroclinic solutions. We will show conditions under

which the homoclinic or heteroclinic orbits persist. We will talk

about the agreement between the analytical results and the direct

numerical computations.
