  • Reprogrammable phononic metasurfaces
    Patent number: 10128439
    Abstract: A phononic transistor can be realized by arranging a row of cantilevered structures with attached magnets, elastically extending upward upon application of a magnetic repulsive force to the magnets. In the extended configuration, the phonons are transmitted from source to drain, while in the flattened configuration the phonons are blocked from transmission. A gate element controls the ON and OFF states of the phononic transistor.
