In a new publication in Nature, we demonstrate that a disordered medium can be made fully transmitting to all incoming waves by placing a suitably tailored complementary medium in front of it. This project was implemented in a fruitful collaboration with the experimental group of Matthieu Davy in Rennes (France). For more information check out the press releases of TU Wien and of Rennes University. Here are also articles in Physics World and in Optics & Photonics News as well as a YouTube video on our work.
