Three-dimensional finite difference split-step nonparaxial beam propagation method: new method for splitting of operators

Debjani Bhattacharya, Anurag Sharma

Abstract

We present a new method for splitting of operators in the three-dimensional finite difference split-step nonparaxial beam propagation method. The method increases the accuracy and the efficiency in terms of speed and memory requirements for three-dimensional wide-angle beam propagation. It also makes the application of the perfectly matched layer (PML) boundary condition very simple.
