Electric-field-sustained spiral waves in subexcitable media.
نویسندگان
چکیده
We present numerical evidence that, in the presence of a suitable electric field, an isolated broken plane wave retracting originally in subexcitable media can propagate continuously and eventually evolve into a rotating spiral. Simulations for the FitzHugh-Nagumo, the Barkley, and the Oregonator models are carried out and the same electric-field-sustained spiral phenomena are observed. Semianalytical results in the framework of a kinematic theory are quantitatively consistent with the numerical results.

Noise sustained waves in subexcitable media: From chemical waves to brain waves.
We discuss a novel type of spatiotemporal pattern that can be observed in subexcitable media when coupled to a thermal environment. These patterns have been recently observed in several different types of systems: a subexcitable photosensitive Belousov-Zhabotinsky reaction, hippocampal slices of rat brains, and astrocyte syncytium. In this paper, we introduce the basic concepts of subexcitable ...
متن کاملWave propagation in subexcitable media with periodically modulated excitability.
Wave propagation in a photosensitive, subexcitable Belousov-Zhabotinsky medium is made possible by periodic modulation of a homogeneous illumination field. The propagation can be understood in terms of an interplay between the radial expansion of the wave and the motion of its free ends as the excitability varies periodically. This description leads to a simple kinematic analysis that provides ...
متن کاملAn Algorithm for Modeling and Interpretation of Seismoelectric Data
Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...
متن کاملEliminate spiral wave in excitable media by using a new feasible scheme
In this paper, a new scheme is proposed to remove the spiral wave in a two-dimensional Fithhugh–Nagumo type equation by introducing a class of vortex electric field into the media. A long electric solenoid with large pipe diameter is used to generate a spatial magnetic field and the intensity of magnetic field B is controllable. A vortex electric field could be induced by changing the external ...
متن کاملDrift of spiral waves controlled by a polarized electric field.
The drift behavior of spiral waves under the influence of a polarized electric field is investigated in the light that both the polarized electric field and the spiral waves possess rotation symmetry. Numerical simulations of a reaction-diffusion model show that the drift velocity of the spiral tip can be controlled by changing the polarization mode of the polarized electric field and some inte...
