Evolution of spiral in light-sensitive media described with the two variable Oregonator model is investigated. The intensity of external illumination is modulated by a weak chaotic signal, which is introduced into the whole system, the additional Bromide production is influenced and the dynamics thus changed. The results are confirmed within our numerical simulation and it may give useful information in pattern formation and suppression of spiral.
Keywords: spiral waves; Oregonator model; BZ reaction; chaotic signal
