Two-Dimensional Metallic Body Scattering Using Method of Moments

This paper presents a two-dimensional metallic body scattering program based on the Method of Moments, elaborating on its fundamental principles and implementation methodology. The introduction provides an overview of scattering problems and detailed explanations of the Method of Moments' principles and advantages. The implementation section describes how to develop the corresponding MATLAB program, focusing on key computational aspects including matrix formulation, boundary condition handling, and integral equation discretization. The complete source code and usage guidelines are provided in the appendix, featuring functions for electromagnetic field calculation, surface current modeling, and far-field pattern generation. Numerical simulations and experimental results validate the program's effectiveness and accuracy, demonstrating proper implementation of moment method discretization and matrix inversion techniques for scattering analysis. This comprehensive approach facilitates better understanding and practical application of the program for electromagnetic scattering studies.
