Abstract : We present a new beam propagation algorithm based upon a Pade approximation of the propagation operator that is accurate at angles of up to 65 degrees from the propagation axis. Ours represents an alternate approach to previous work in which the square root Helmholtz operator was first expanded and then approximated.
