Transmission Matrix Method for Calculating Transmittance in Photonic Crystals

We have developed a MATLAB-based program utilizing the transmission matrix method to calculate the transmittance of photonic crystals as a function of incident angle. The implementation features layered matrix multiplication algorithms to model light propagation through periodic dielectric structures. The complete code is contained within a Word document that includes detailed implementation guidelines, parameter configuration examples, and supporting diagrams. This program serves as a valuable research tool that not only computes transmittance spectra but also demonstrates the fundamental working principles of photonic crystals and transmission matrix methodology. The code incorporates angle-dependent boundary condition handling and employs efficient matrix operations for multilayer structure analysis. Please refer to the accompanying documentation for instructions on program execution, parameter adjustment, and result interpretation to enhance your research depth and comprehensiveness in photonic bandgap studies.
