title: Beam-propagation method based on the Wigner transform: a new formulation.
abstract: A new formulation of the classical scalar beam-propagation method is derived by use of the Wigner transform. The new method is faster than the classical beam-propagation method because no Fourier transform must be computed. An example given to illustrate the proposed method shows additional advantages.
