An international team of researchers has developed a way to create non-radiating sources of electromagnetism. In their paper published in the journal Physical Review Letters, the group describes their technique and how well ...
By cleverly analyzing the results, the algorithm can deduce the shape, size and layout of a room, as well as pick out in the presence of objects or people. The results are displayed as a video feed which turns the echo data ...
