“What can you do with these? The authors demonstrated that it should be possible to construct devices that take the derivative and the second-order derivative of the light wave's curve. Those could be used to perform edge detection on the image. It was also possible to perform convolutions, merging the function that describes the light's wavefront with one encoded by the metamaterial. As with other analog computers, regardless of what math was being performed, the output would update instantly as the light would change. These aren't especially useful at the moment, but the authors haven't demonstrated that they can build a working device yet, either. Once they do, it's possible that they and others will put some serious thought into how to get something useful out of it.” - × × ×
