Small- and nano-scale soft phononics
Abteilung Physik der Grenzflächen, Forschungsgruppe Phononik weicher Materie
Summary1993, twelve years after the discovery of photonics, was the birth of phononic materials for the controlled propagation of mechanical/acoustic waves. The first experimental realization followed in soon after at sonic and later at hypersonic frequencies using macromachinery and soft matter self-assembly. Two examples, artificial and natural hierarchical structures, will highlight the new emerging field of high frequency phononics aiming at tunable strong, deaf, cool and interactive materials.
