Abstract We solve the Cauchy problem for the n-dimensional wave equation using elementary properties of the Fourier transform. The Monthly publishes articles, as well as notes and other features, ...

Combining white light interferometry with Fourier scatterometry provides an optical metrology tool for characterizing subwavelength structures. Valeriano Ferreras Paz and co-workers from Stuttgart ...

But Fourier transforms are the workhorses in many modern fields of science, including data processing, image analysis, optics, communication, astronomy and engineering.
