Adaptive stepsize algorithm for Fourier beampropagation method with absorbing boundary layer of autodetermined width
Abstract
Two algorithms that enhance the utility of the absorbing boundary layer are presented, mainly in the framework of the Fourier beampropagation method. One is an automated boundary layer width selector that chooses a nearoptimal boundary size based on the initial beam shape. Furthermore, the second algorithm adjusts the propagation step sizes based on the beam shape at the beginning of each step in order to reduce aliasing artifacts.
