Ultrafast dynamics and sub-wavelength periodic structure formation following irradiation of GaAs with femtosecond laser pulses
A. Margiolakis, G. D. Tsibidis, K. M. Dani +1
A theoretical investigation of the ultrafast processes and dynamics of the excited carriers upon irradiation of GaAs with femtosecond (fs) pulsed lasers is performed in conditions…
Enhanced surface plasmon polariton propagation induced by active dielectrics
C. Athanasopoulos, M. Mattheakis, G. P. Tsironis
We present numerical simulations for the propagation of surface plasmon polaritons in a dielectric-metal-dielectric waveguide using COMSOL multiphysics software. We show that the u…
Nonlinear Localization in Metamaterials
N. Lazarides, G. P. Tsironis
Metamaterials, i.e., artificially structured ("synthetic") media comprising weakly coupled discrete elements, exhibit extraordinary properties and they hold a great promise for nov…
Gain-Driven Discrete Breathers in PT-Symmetric Nonlinear Metamaterials
N. Lazarides, G. P. Tsironis
We introduce a one dimensional parity-time (PT)-symmetric nonlinear magnetic metamaterial consisted of split ring dimers having both gain and loss. When nonlinearity is absent we f…
Surface magnetoinductive breathers in two-dimensional magnetic metamaterials
Maria Eleftheriou, Nikos Lazarides, George P. Tsironis +1
We study discrete surface breathers in two-dimensional lattices of inductively-coupled split-ring resonators with capacitive nonlinearity. We consider both Hamiltonian and dissipat…
Magnetoinductive breathers in magnetic metamaterials
M. Eleftheriou, N. Lazarides, G. P. Tsironis
The existence and stability of discrete breathers (DBs) in one-dimensional and two-dimensional magnetic metamaterials (MMs), which consist of periodic arrangem ents (arrays) of spl…
