From: Acoustic cloak based on Bézier scatterers

Figure 2

Dependence of the fitness function with the number of scatterers contained in the cloak. Three type of scatterers have been considered in the optimization procedure: Bézier scatterers (diamond symbols), scatterers with circular sections of equal radii (hollow squares) and scatterers with circular sections but variable radii (hollow circles). F = 1 means perfect concealing of the central object.
