Lorenzo Sanchis works at UMDO (Unit of Optoelectronic Materials and Devices) of the Institute for Materials Science (University of Valencia) and has coordinated the research group that developed the first acoustic invisibility cloak that works on three-dimensional objects, particularly spheres. This means that objects are impermeable to sound waves which are diverted in other directions. The experiment has been carried out as part of a joint project by researchers from the University of Valencia (theoretical design of the invisibility cloak) and the Polytechnic University of Valencia (testing). Sanchis also took part in the development of an acoustic lens capable of concentrating sound on a particular point, a tool that, once perfected, could be applied to fight acoustic pollution. Somehow shy and quite nervous he confessed «This is my first press interview».
According to the information published in your article1, similar tests have previously been run. How does your research build on existing knowledge of acoustic camouflage?
What is the invisibility mechanism made up of and how does it work?
What is a genetic algorithm?
How long can the calculations to obtain this effect take?
That would have been unconceivable twenty years ago…

What type of object does the invisibility cloak work with nowadays?
Would it be useful in airports?
