[EN] This Letter presents practical realization of a two-dimensional low loss acoustic cloak for airborne
sound obtained by inverse design. The cloak consists of 120 aluminum cylinders of 15 mm
diameter surrounding the cloaked object¿a cylinder of diameter 22.5 cm. The position of each
cylinder in the cloak is optimized using the data from two different techniques: genetic algorithm
and simulated annealing. The operation frequency of this cloak is 3061 Hz with the bandwidth of
about 100 Hz. Being a multi-step approach to the desired cloaking, the inverse design is also valid,
in principle, for non-symmetric cylinders and even for three-dimensional objects. VC 2011 American
