3-D Metamaterial Model (IMAGE) DOE/Ames National Laboratory Caption Shown here is a model of a 3-D metamaterial structure. Metamaterials are engineered materials that exhibit properties not possible in natural materials, like reflecting light to the same side as incidence normal, absorbing all light that hits them, and slowing light.
