Australian National University (ANU) physicists have developed new tech that controls the direction that light can and cannot travel in using nanoparticles, possibly discovering the path to cheaper, faster and more reliable internet.
In collaboration with colleagues from Singapore, China and Germany, ANU scientists have developed small translucent slides that produce two different images, depending on the direction that light passes through them. For example, at first, a slide may produce an image of a microscope but once it is flipped it produces an image of a collection of wheels and cogs, and this is but one of a large number of possibilities.
