A study developed by researchers from the Universitat Politècnica de València (UPV), associated with the Nanophotonics Technology Center (NTC) and the company DAS Photonics, promises to revolutionize the design of so-called invisibility cloaks. With their proposal, these cloaks will no longer be so invisible. And the key is simple: applying diffraction tomography techniques to detect these devices. Their work has been published in the journal Laser & Photonics Reviews.
