The geometry of an active medium can cause wave blocking and induce unidirectional propagation. This well established phenomenon was studied in a previous paper within the framework of the photosensitive Belousov-Zhabotinsky reaction and the associated Oregonator model. In the present paper, as an extension of that study, the main factors that influence this phenomenon are interpreted in terms of a kinematic model.

The length of the wave calculated from Eq. (1) is obtained first locating the maximum of the field along the direction of propagation and then adding up those points above a threshold chosen to be (a perturbation below this value is unable to spread by diffusion).
