Abstract
A novel finite element method (FEM) based wide-angle (WA) beam propagation method (BPM) was presented whereby the scalar Helmholtz equation was solved without using the slow varying envelope approximation (SVEA) and was more general and precise than the previous well-known WA-BPM proposed by Hadley. The accuracy of this novel scheme was demonstrated in comparison with the existing approach.
