Abstract
We have observed spatio-temporal intermittency in two-dimensional patt erns obtained from simulations of the complex Ginzburg-Landau equation (CGLE) under pinning control. Pinning is applied to selected local si tes to control spatio-temporal chaos in slightly disordered systems. W e obtained concentric circular patterns, which are stable or in some c ases intermittent, as a result of this control. Effectiveness of the p inning control strongly depends on the pinning density.
