Chaotic-like behavior of modulated waves in a nonlinear discrete LC transmission line

Modulational instability (MI) in a discrete nonlinear LC transmission line is investigated. The higher order nonlinear Schrödinger (NLS) equation modeling modulated waves propagation in the network allows to predict the MI conditions, with additional features, compared to the standard NLS model. More precisely, a chaotic-like behavior of the system, which is observed in a particular frequency domain, is related to the nonrepeatability of the numerical experiments.
