Abstract

A wide-angle Beam Propagation Method (BPM) based on the series expansion technique is proposed. The method employs a finite difference approach and allows extremely dense discretizations. A theoretical analysis supporting this numerical technique is demonstrated. Semi-vectorial formulations are included in this BPM algorithm. It is easily applicable to 3-D simulations. Following an accuracy test with a 2-D problem, several 3-D examples for quasi-TE and -TM modes are demonstrated
