It is now possible to calculate the Fourier transform of an image on your smartphone, thanks to a new app developed by two nanophotonics researchers in The Netherlands. “2D-Fourier” is available for ...

A key algorithm that quietly empowers and simplifies our electronics is the Fourier transform, which turns the graph of a signal varying in time into a graph that describes it in terms of its ...

The notion of Fourier transform is among the most important tools in analysis, which has been generalized in abstract harmonic analysis to the level of abelian locally compact groups. The aim of this ...
