Coupled nonlinear Schrodinger field equations for electromagnetic wave propagation in nonlinear left-handed materials.
For isotropic and homogeneous nonlinear left-handed materials, for which the effective medium approximation is valid, Maxwell's equations for electric and magnetic fields lead naturally, within theExpand

Magnetoinductive breathers in metamaterials.
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 resonators (SRRs), areExpand

Discrete breathers in nonlinear magnetic metamaterials.
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 model one-dimensionalExpand

Self-focusing and envelope pulse generation in nonlinear magnetic metamaterials.
The self-modulation of waves propagating in nonlinear magnetic metamaterials is investigated. Considering the propagation of a modulated amplitude magnetic field in such a medium, we show that theExpand

Josephson effect in double-barrier superconductor-ferromagnet junctions
We study the Josephson effect in ballistic double-barrier SIFIS planar junctions, consisting of bulk superconductors (S), a clean metallic ferromagnet (F), and insulating interfaces (I). We solve theExpand

$\mathcal{PT}$-symmetric nonlinear metamaterials and zero-dimensional systems
A one dimensional, parity-time ($\mathcal{PT}$)-symmetric magnetic metamaterial comprising split-ring resonators having both gain and loss is investigated. In the linear regime, the transition fromExpand
