Inspired by acoustics, a French-US team has found a way to locate objects in a room simply by their microwave scattering characteristics. Similar to diffusing reverberant acoustic wave spectroscopy (DRAWS), the techniques relies on the room having walls that reflect radio waves – reflecting sufficiently to fill the room with a complex field of interference ...
