The effect of a finite geometry in the two-dimensional complex Ginzburg-Landau equation is addressed. The presence of boundaries induces the formation of novel states. Target like-solutions appear as robust solutions under Dirichlet boundary conditions. Synchronization of plane waves emitted by boundaries, entrainement by corner emission, and
anchoring of defects by shock lines is also reported.
