Abstract: Hexagonal sampling is the most efficient sampling pattern for a two-dimensional circularly bandlimited function. A separable fast discrete Fourier transform (DFT) algorithm for hexagonally ...

Abstract: A novel technique based on the Fourier transform is applied to analyze a ridge waveguide and rectangular coaxial line. On the basis of the image theorem the ridge waveguide and rectangular ...

This is part of the project for my final project for the BSc Mathematics at Queen Mary, University of London. It contains my implementation of the Fast Fourier Transform, a denoising function and an ...
