Rectangular Waveguide Simulation with MATLAB

This project focuses on simulating rectangular waveguides using MATLAB, with detailed implementation of electromagnetic wave propagation models. The simulation of waveguides is crucial for modern communication systems design, making this research highly relevant for practical applications. Through MATLAB coding, we implement numerical solutions to Maxwell's equations to analyze waveguide behavior.

Our methodology begins with a thorough literature review to identify research gaps and establish project scope. We then develop a mathematical model based on electromagnetic theory, which will be implemented using MATLAB's PDE toolbox or custom finite-difference methods. The model incorporates waveguide geometry specifications and material properties through parameterized functions.

Using MATLAB, we simulate electromagnetic wave propagation through various waveguide configurations. Key implementation aspects include: defining waveguide dimensions as input variables, implementing frequency-domain analysis using eigenmode solvers, and applying different boundary conditions through matrix manipulations. We analyze parameters like cutoff frequencies using eigenvalue calculations and visualize field distributions using contour plots and 3D graphics. The code includes sensitivity analysis functions to study how dimension variations and operating frequencies affect wave propagation characteristics.

This project provides a framework for rectangular waveguide analysis using computational electromagnetics techniques in MATLAB. The implementation offers modular code structure for easy parameter modification and result visualization, contributing to both educational and research applications in waveguide theory.
