Periodically Forced Nonlinear Oscillatory Acoustic Vacuum
Makrina Agaoglou, Michal Feckan, Michal Pospisil +2
In this work, we study the in-plane oscillations of a finite lattice of particles coupled by linear springs under distributed harmonic excitation. Melnikov-type analysis is applied…

Travelling waves in nonlinear magneto-inductive lattices
M. Agaoglou, M. Feckan, M. Pospisil +2
We consider a lattice equation modelling one-dimensional metamaterials formed by a discrete array of nonlinear resonators. We focus on periodic travelling waves due to the presence…

Gain-loss-driven travelling waves in PT-symmetric nonlinear metamaterials
M. Agaoglou, M. Feckan, M. Pospisil +2
In this work we investigate a one-dimensional parity-time (PT)-symmetric magnetic metamaterial consisting of split-ring dimers having gain or loss. Employing a Melnikov analysis we…
