Webb5 sep. 2012 · The Split-step Fourier Method A standard way to numerically solve certain differential equations is through the use of the Fourier transform. We'll use a Fourier convention of the following form: ψ ~ ( k, t) = 1 2 π ∫ − ∞ ∞ ψ ( x, t) e − i k x d x Under this convention, the associated inverse Fourier Transform is given by: WebbTeachSpin is dedicated to the design, manufacture, marketing and support of rugged, reliable, hands-on laboratory instruments that enable any school, no matter what the …
