The idea of an invisibility cloak has long fascinated the human mind, and so far, these have only appeared in fantasy and science fiction settings. So far, all the experiments concerning such “invisibility cloaks” play around on the same concept – to curve light that comes from behind an object around it, where said light will continue making its way to the viewer. This means the person will be able to see what is behind the object instead of the object itself. How about applying a similar principle to sound waves.
