FDTD Computation of Two-Dimensional Photonic Band Gaps

This repository contains an excellent set of Finite-Difference Time-Domain (FDTD) programs specifically designed for computing two-dimensional photonic band gaps. The codebase is fully compatible with MATLAB version 7.0 and later releases. Beyond photonic band gap calculations, these programs can be adapted to explore various photonics-related research areas, including applications in sensor technology and optical communications. The implementation features key FDTD components such as Yee grid discretization, perfectly matched layer (PML) boundary conditions, and Fourier transform-based frequency analysis. Users can easily modify the source code to accommodate specific research requirements, thanks to the well-structured MATLAB functions and clear algorithmic organization. Notably, the programs are designed with user-friendliness in mind - no advanced programming expertise is required to achieve significant research outcomes, making them accessible to researchers across different technical backgrounds.
