- PublicationOptical wave propagation simulation, Wigner phase-space diagrams, and wave energy confinement(Optical Society of America, 2005-10-16)
; ; The number of samples required for efficient numerical simulation of wave propagation can be determined by a combination of Wigner phase-space techniques, wave energy confinement arguments, and a theorem relating energy confinement to accuracy.357 - PublicationWigner cross-terms in sampled and other periodic signalsIf we sample a scalar wave field, it becomes periodic in frequency. We examine the cross-terms which occur between these periodic replicas in the Wigner-Ville distribution function of such a signal. We present analytic results for Gaussian signals. The results also have implications for physical systems which contain periodic gratings.
