Pulses, Fronts and Chaotic Wave Trains in a One-dimensional Chua’s Lattice

چکیده
We show how wave motions propagate in a nonequilibrium discrete medium modeled by a onedimensional array of diffusively coupled Chua’s circuits. The problem of the existence of the stationary wave solutions is reduced to the analysis of bounded trajectories of a fourth-order system of nonlinear ODEs. Then, we study the homoclinic and heteroclinic bifurcations of the ODEs system. The lattice can sustain the propagation of solitary pulses, wave fronts and complex wave trains with periodic or chaotic profile.

Wave propagation along interacting fiber-like lattices
A fiber-like lattice with resistively coupled electronic elements mimicking a 1-D discrete reactiondiffusion system is considered. The chosen unit or element in the fiber is the paradigmatic Chua’s circuit, capable of exhibiting bistable, excitable, oscillatory or chaotic behavior. Then the dynamics of a structure of two such interacting parallel active fibers is studied. Suitable conditions fo...
متن کاملObservations of phase Synchronization Phenomena in One-Dimensional Arrays of Coupled Chaotic Electronic Circuits
In nature, structures composed of individual simple subsystems are wide-spread. Specific examples come from biology and medicine (tissues of living organisms) physics and chemistry (matter composed of atoms), etc. Properties of such systems depend on properties of individual subsystems and the way they are coupled together. Various models describing behavior of interconnections of a large numbe...
متن کاملRegular Pulse Trains in Chaotic pulse Bursts
Electric field pulse bursts generated by lightning flashes are considered as sources of high radio frequencies. In this study, an analysis of pulse bursts in electric field records of 30 negative cloud to ground lightning flashes recorded in the southern coastal area of Sri Lanka is presented. Sixty-four percent (64%) of pulse bursts are typical chaotic pulse trains (CPT). Twenty-four percent (...
متن کاملExponential Stability of Traveling Fronts for a 2d Lattice Delayed Differential Equation with Global Interaction
The purpose of this paper is to study traveling wave fronts of a two-dimensional (2D) lattice delayed differential equation with global interaction. Applying the comparison principle combined with the technical weighted-energy method, we prove that any given traveling wave front with large speed is time-asymptotically stable when the initial perturbation around the wave front need decay to zero...
متن کاملCharge gradient effects on modulated dust lattice wave packets in dusty plasma crystals
Nonlinear Dust lattice modes are studied in a hexagonal two-dimensional dusty plasma lattice, in presence of charge gradient of dust particles. In this lattice, such gradients affect nonlinear behavior of dust lattice waves. The amplitude modulation of off-plane transverse dust lattice wave packets is investigated considering the anisotropy of interactions, caused by the height-dependent char...
