摘要: Wave front propagation failure is investigated in discrete bistable reaction-diffusion systems. We present a theoretical approach including dissipative effects and leading to an analytical expression of the critical coupling beyond which can occur as function nonlinearity threshold parameter. Our predictions are confirmed by numerical simulations experimental results on equivalent electrical diffusive lattice.
