A wave manipulation concept developed at TU Wien has now been tested for the first time in an experiment. The technique allows sound waves to be guided effortlessly through complex structures. We are constantly dealing with waves that are deflected in complex ways: this could be a light beam passing through a glass of milk and being dispersed in all directions, or electromagnetic waves from mobile phone masts being dispersed or absorbed, causing us to complain about poor reception in indoor areas. Researchers at TU Wien are developing methods for manipulating waves in a targeted manner, so that they can move forward with almost no restriction. In a partnership with research groups from the École Polytechnique Fédérale de Lausanne (EPFL) and the University of Crete, this method has now been implemented in an experiment. Using precisely controlled loudspeakers, it has been possible to send a sound wave through a tube containing various obstacles. In the long term, technologies like this could enable light waves to be manipulated and objects to be made invisible.
