Source Code for Fresnel Diffraction

This document presents the source code for Fresnel diffraction, a highly practical algorithm for simulating wave propagation phenomena. Fresnel diffraction describes the physical behavior of light waves when passing through irregular obstacles or apertures. The implementation features efficient numerical computation methods, potentially utilizing Fast Fourier Transform (FFT) techniques for optimal performance. This algorithm finds applications across multiple domains including acoustic and electromagnetic wave propagation simulation, as well as computer graphics for realistic light rendering and optical effects simulation. The code structure likely includes key functions for wavefront propagation calculation, aperture modeling, and intensity distribution computation. Researchers and developers working with wave physics simulations will find this documentation particularly valuable. The author emphasizes the algorithm's user-friendly implementation, making it an accessible tool for both academic research and industrial applications in optics and wave-based simulations.
