Parabolic Equation Ray Tracing MATLAB Code Implementation for 2026 Wave Propagation Analysis

"The Parabolic Equation (PE) method serves as the industry standard for modeling wave propagation in complex, inhomogeneous media, particularly in underwater acoustics and radio frequency (RF) propagation over terrain. This guide focuses on the implementation of split-step Fourier PE algorithms in MATLAB for 2026 research standards. Foundational Principles of PE-Based Wave Modeling The parabolic equation approximation is derived from the Helmholtz equation by assuming that wave energy primarily propagates along a preferred direction, typically the horizontal axis. This reduction transforms an elliptic boundary value problem into a parabolic in..."
