Pulse Wave Propagation in a Large Number of Coupled Bistable Oscillators
نویسندگان
چکیده
A simple model of inductor-coupled bistable oscillators is shown to exhibit pulse wave propagation. We demonstrate numerically that there exists a pulse wave which propagates with a constant speed in comparatively wide parameter region. In particular, the propagating pulse wave can be observed in non-uniform lattice with noise. The propagating pulse wave can be observed for comparatively strong coupling case, and for weak coupling case no propagating pulse wave can be observed (propagation failure). We also demonstrate various interaction phenomena between two pulses. key words: bistable oscillators, inductor coupling, pulse propagation/interaction phenomena, non-uniform lattice, propagation failure

Pulse Wave Propagation in Bistable Oscillator Array
A study of propagating wave phenomenon in coupled systems is one of the familiar topics of research. There exist propagating wave phenomena in various systems such as reactiondiffusion systems (Nishiura et al.; 2005; Comte et al.; 2001), coupled map lattice (Kaneko; 1993) and coupled oscillator systems (Hikihara et al.; 2001; Yamauchi et al.; 1999), etc.. They are important not only in a pure n...
متن کاملUnique Solution of Short Pulse Propagation in Nonlinear Fiber Bragg Grating
In this study, a new numerical method is introduced to obtain the exact shape of output pulse in the chalcogenide fiber Bragg grating (FBG). A Gaussian pulse shape with 173 ps width is used as an input pulse for lunching to a 6.6 mm nonlinear FBG. Because of bistable and hysteresis nature of nonlinear FBG the time sequence of each portion of pulse is affected the shape of output pulse. So we di...
متن کاملSimulation of Wave Propagation over Coastal Structures Using WCSPH Method
In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
متن کاملPulse Wave Propagation and Interaction Phenomenon in a Large Number of Coupled van der Pol Oscillator Lattice
In this paper, we investigate pulse wave propagation and pulse wave interaction phenomenon in a large number of coupled van der Pol oscillator lattice with hard-type nonlinearity. We demonstrate numerically that there exists a pulse wave which propagates with a constant speed, when ε (= a parameter which shows the degree of nonlinearity) exceeds a certain critical value. Moreover, We find that ...

In this study, wave propagation phenomena of phase states are observed at van der Pol oscillators coupled by inductors as a ladder. For the case of 17 oscillators, interesting wave propagation phenomena of phase states are found. By using the relationship between phase states and oscillation frequencies, the mechanisms of the propagation and the reflection of wave are explained. Circuit experim...
