Abstract

A new beam-propagation scheme based on a finite-difference algorithm is proposed. The main property of this scheme is to avoid the boundary conditions altogether, by mapping the infinite space onto a finite-size domain. This mapping, together with a rescaling of the field, leads to a fast and easy-to-implement algorithm that can be used when boundary condition constraints are important.
