3D Metamaterials
Metamaterials are designed artificial materials the properties of which go beyond (meta) those of their ingredient materials. "Solid-State Physics 2.0". After a general introduction, I will discuss selected examples from optics, mechanics, electromagnetism, and transport.



![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
