Simulation of Waveguide Modes in Multilayer Planar Waveguides

I have developed a MATLAB program to simulate waveguide propagation in multilayer planar waveguides. The implementation includes comprehensive modeling for both TE (Transverse Electric) and TM (Transverse Magnetic) modes using eigenvalue solving techniques and boundary condition matching algorithms. While the current program provides practical functionality, it offers significant expansion capabilities through modular code design. By incorporating additional parameters and variables, such as material dispersion models and loss coefficients, we can achieve more accurate waveguide behavior analysis and enhanced modeling precision. The object-oriented architecture allows for straightforward adaptation to other waveguide types, enabling comparative studies of different waveguide structures and their propagation characteristics. The core algorithm utilizes transfer matrix methods to handle multiple dielectric layers efficiently, with separate mode solvers implementing the characteristic equations for TE and TM polarization states. This program serves as a valuable computational tool for understanding and researching waveguide propagation phenomena, with potential applications in integrated photonics and optical communication system design.
