Abstract: In crystallography one has to compute finite Fourier transforms that are often very large and often respect crystallographic symmetries. In this paper we discuss efficient finite Fourier ...
The discovery, centred around controlling tiny hurricanes of light and electromagnetic fields, could revolutionise how much information we can deliver over cables.
Much of modern life depends on the coding of information into means of delivering it. A common method is to encode data in laser light and send it through optic cables. The increasing demand for more ...
