SQUID Metamaterials: Tuneability and Multistability
G. P. Tsironis, N. Lazarides
An overview of several dynamic properties of SQUID metamaterials is given in the presence of both constant and alternating magnetic field. The total current as a function of the dr…
Extreme Events in Nonlinear Lattices
G. P. Tsironis, N. Lazarides, A Maluckov +1
The spatiotemporal complexity induced by perturbed initial excitations through the development of modulational instability in nonlinear lattices with or without disorder, may lead…
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…
Multistability and Self-Organization in Disordered SQUID Metamaterials
N. Lazarides, G. P. Tsironis
Planar arrays of magnetoinductively coupled rf SQUIDs belong to the emergent class of superconducting metamaterials that encompass the Josephson effect. SQUID metamaterials acquire…
