Highly non-linear metamaterials for laser technology |

| Non-linear optical materials
: 03 July, 2014 |
|
Non-linear optical materials are widely used in laser systems. However, high light intensity and long propagation are required to produce strong non-linear optical effects. Researchers at The University of Texas at Austin and the Technische Universitaet Muenchen have created metamaterials with a million times stronger non-linear optical response, compared to traditional non-linear materials, and demonstrated frequency conversion in films 100 times thinner than a human hair, using light intensity comparable to that of a laser pointer. |

| Vibration-Damping Structures
: 10 March, 2014 |

Researchers from Empa and ETH Zurich have succeeded in producing a prototype of a vibration-damping material that is not only able to damp vibrations completely, but it can also specifically conduct certain frequencies further. Although the "programmable material’ still only works in a one-dimensional model construction, it has already demonstrated its unusual capabilities. |
