Light, sound, and now, heat -- just as optical invisibility cloaks can bend and diffract light to shield an object from sight, and specially fabricated acoustic metamaterials can hide an object from sound waves, a recently developed thermal cloak can render an object thermally invisible by actively redirecting incident heat. The system, designed by scientists in Singapore and described in this week's Applied Physics Letters, has the potential to fine-tune temperature distribution and heat flow in electronic and semiconductor systems.
