Summary:
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 collision of these pulse waves result in various phenomena such as repulsion, unification, disappearance, standing waves, etc. depending on the value of ε.
