The renown physicist describes his breakthroughs in designing metamaterials and cloaking objects, in “Scientific American.”

Creating metamaterials that trick sound and light may sound more like science fiction than science, but that is what Distinguished Professor Andrea Alù (Physics), founding director of the Photonics Initiative at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC), does in his research. In a new article in Scientific American, the eminent physicist, a Blavatnik National Awards Laureate, describes in plain language his far-out inventions.

As Alù explains, metamaterials are materials that are engineered to “move beyond the traditional ways in which waves and matter interact, creating technologies where light and sound appear to disobey conventional rules.” He delves into the metamaterials that he and his colleagues have created, how these materials manipulate sound and light, and their many potential applications.
