Abstract: [EN] A theoretical and experimental study of the propagation of sound beams in- and behind three-dimensional sonic crystals at frequencies close to the band edges is presented. An efficient collimation of the beam behind the crystal is predicted and experimentally demonstrated. This effect could allow the design of sources of high spatial quality sound beams. © 2012 American Institute of Physics.<br />The work was financially supported by Spanish Ministry of Science and Innovation and by European Union FEDER through projects FIS2008-06024-C02-02, -03 and MAT2009-09438.
