Martin Wegener has a joint appointment as professor of physics at Universität Karlsruhe (TH) and Forschungszentrum Karlsruhe GmbH. He is also coordinator of the DFG-Center for Functional Nanostructures (CFN) at Universität Karlsruhe (TH). His current research interests comprise photonic metamaterials, photonic crystals, and nanophotonics.
Metamaterials can be designed to rotate light as it passes through them. If the effect is strong enough, it can lead to the material having a negative index of refraction and light bouncing around very differently than expected. Read More »
