  • A new scheme is proposed to suppress stable and meandering spiral waves in excitable media by generating a self-exciting target wave in a local area. An arbitrary selected grid in the media is sampled, and the sampled signal is fed back into a local area in the media. Numerical simulation results confirm its effectiveness when the scheme is introduced into anisotropic (the diffusion coefficient is perturbed vs. time and/or space) and isotropic media. Results also show the scheme's robustness to spatiotemporal noise.

Abstract: A new scheme is proposed to suppress stable and meandering spiral waves in excitable media by generating a self-exciting target wave in a local area. An arbitrary selected grid in the media is sampled, and the sampled signal is fed back into a local area in the media. Numerical simulation results confirm its effectiveness when the scheme is introduced into anisotropic (the diffusion coefficient is perturbed vs. time and/or space) and isotropic media. Results also show the scheme's robustness to spatiotemporal noise.
