Scientists in Greece, Austria, and the USA have teamed up to research an innovative invisibility technology. This new technology offers a whole new range of possibilities for artists that study camouflage. Thanks to a special material and suitable illumination, another beam of light is able to pass through. This beam can illuminate it from above. The result is that this object is not visible to the person viewing it.
Researchers from the Vienna University of Technology and the University of Crete collaborated for this. The team led Professor Stefan Rotter and Assistant Professor Konstantinos Makris. They believe in the application of their new method to various wavelengths of light.
There are a lot of teams across the world working on invisibility technology. Different kinds of materials, called meta-materials, can take light around items in order to make them undetectable by someone looking.
An interesting technique is to use engineered objects that work to amplify or mute the light coming from outside. An electronic screen can help for the effect. This can make an object invisible if viewed from a certain angle and wavelength.
These researchers next shot a laser through the object rather than around it. Although it sounds pretty strange, you can actually use radiation attenuation and amplification with a specific type of wave to create special materials.
Computer simulations have been done so far, and the technique looks like it can really work. Scientists are already planning to carry out experiments to confirm this in practice. They may start with acoustic waves rather than light waves because the latter are considered easier to handle in an experimental sense.
Gather more information on the Professors. K. Makris studied at the NTUA School of Electrical Engineering for 2 years and received his PHD in theoretical physics from the University of Central Florida, USA in 2008. Between 2008-2010 he did postdoctoral research at the Federal Polytechnic School of Lausanne (EPFL) in Switzerland, then lectured at the Vienna University of Technology (TU-Wien) before moving to Princeton University for three years. In 2017 he became an assistant professor at the Physics Department of the University of Crete
