Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
Negative light may be about to change communication forever. Instead of scrambling the information in the message, this approach hides the actual signal sending the data. It lays the blueprint for a ...
Researchers at the University of UNSW Sydney and Monash University have demonstrated a communication method that hides data transfers inside natural thermal radiation. The approach (which appears in ...
