Nanophotonics

Welcome to the website of Prof. Dr. Martin Wegener's research unit "Nanophotonics" at the Institute of Nanotechnology.

Our research focuses on the fabrication and characterization of novel functional materials - so called metamaterials. Therefore, we develop advanced lithography and replication approaches to fabricate such materials and devices.

An elasto-mechanical unfeelability cloak made of pentamode metamaterials

KIT researchers have created the first mechanical invisibility cloak. When placed over an object, the object cannot be felt at all — either by a finger, or a more sensitive measuring device.

Invisibility cloaking in a diffusive light scattering medium

Researchers at the KIT have developed a cloak that is broadband, omnidirectional, and big enough to hide a macroscopic object. The new cloak works  in foggy or "diffusive" conditions.
