Combining theoretical, modeling/simulation and experimental approaches, Materials Science and Engineering Professor Pierre Deymier is developing news ways of manipulating sound waves. He and his colleagues have discovered that when sound passes through particular media, its properties change. One can make flat lenses for focusing sound, or make forms of sound that propagate in one direction, but not in opposite direction. These properties and others are being harnessed in new applications as diverse as attenuating noise pollution, ultrasound imaging and making sound-wave-based diodes for computer chips.
