The concept — a kind of one-way mirror for sound — seems imaginary, but two Italian scientists recently pushed this kind of sound manipulating technology closer to reality (abstract)."

  1. Wave diode applicable to light? by Garble+Snarky · · Score: 3, Informative

    The article describes the proposed theoretical mechanism as a "wave diode" - I wonder if the same principle is applicable to light? I don't know if "light diodes" already exist in some sense, but that seems like a possibly useful component for optical computing...?

    I'm not sure what this had to do with sound, but what you're thinking of already exists and it's called a peltier.
