Sullivan's Classic MATLAB FDTD Tutorial Source Code

This text references Sullivan's classic MATLAB FDTD tutorial source code. This course covers the Finite-Difference Time-Domain (FDTD) method, a numerical simulation technique used for solving partial differential equations in various physical problems. The implementation typically involves discretizing Maxwell's equations using central-difference approximations in both space and time domains, with careful handling of boundary conditions through techniques like Perfectly Matched Layers (PML). FDTD finds extensive applications across multiple fields including electromagnetics, optics, acoustics, and biomedical engineering. For those interested in these domains, I recommend studying the FDTD method. Sullivan's classic MATLAB FDTD tutorial source code serves as an excellent starting point, where you can examine the core implementation including: - Field update equations using Yee's grid staggering technique - Source excitation mechanisms (hard source/soft source implementations) - Material property assignments and constitutive relations - Visualization routines for electromagnetic field propagation By studying the source code, you can gain deep insights into FDTD's working principles. Furthermore, you can experiment with code modifications and run simulations to enhance your understanding of the method's implementation details, such as adjusting spatial discretization (dx, dy, dz) and observing Courant stability condition effects. Good luck with your computational electromagnetics exploration!
