  • 32nd Primakoff Lecture: "Metamaterials and Topological Mechanics"

    David Rittenhouse Laboratory, A8

    Metamaterials are materials engineered to have a property or properties not found in nature, such as a negative optical index of refraction, one-way light or vibration waves, or exotic elastic behavior.  Advances in materials processing, like 3D printing and laser cutting, over the last 10 to 15 years have made it possible to fabricate metamaterials with made-to-order structure at length scales as short as a micron.
