Researchers have constructed a “metamirror” device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror and only seeing the person next to you instead of your own face. With a regular mirror, the light follows the Law of Reflection — it must bounce off of it at the same angle at which it entered. The same rules generally apply to sound. To break the law of reflection with sound waves, the researchers engineered a device that could precisely control amplitude (loudness) and speed throughout the entire wave.
