Figure 4

Dependence of traveling speed on and pulse width . Symbols and represent simulation results of the RD system (1) in the case of and 3, respectively. (a) Dependence of speed on . Solid curve represents the case of and which connects with the unstable branch (dotted curve) at (). Dashed curve represents the case of with .4. . (b) Dependence of speed on . Solid and dashed curves represent the cases of and with .4, respectively.
