Computation of 2D Fourier transforms and diffraction integrals using Gaussian radial basis functions
We implement an efficient method of computation of two dimensional Fourier-type integrals based on approximation of the integrand by Gaussian radial basis functions, which constitute a standard tool in approximation theory. As a result, we obtain a rapidly converging series expansion for the int...
