Two-Way Propagation Modeling in Waveguides With Three-Dimensional Finite-Element and Split-Step Fourier-Based PE Approaches

Two-way, three-dimensional finite element and split-step Fourier-based parabolic equation (PE) wave propagation prediction algorithms are developed, and MATLAB-based simulators are introduced. The simulators are calibrated against analytical exact data derived from modal summation through tests inside rectangular waveguides.
