MATLAB Analysis of 2D-TE Plane Wave Scattering by Metallic Cylinder

This article presents a comprehensive MATLAB implementation for analyzing the scattering field when a 2D transverse electric (TE) plane wave interacts with a metallic cylinder. We begin by explaining fundamental concepts including plane wave propagation characteristics and metallic boundary conditions. The core implementation involves MATLAB coding techniques for simulating electromagnetic scattering phenomena, where we detail key computational aspects such as the method of moments discretization, boundary condition enforcement, and far-field/near-field calculations. For each code segment, we clarify parameter significance including cylinder radius, wave frequency, and spatial resolution settings. The implementation utilizes MATLAB's powerful matrix operations and visualization tools to efficiently compute and display field distributions. Furthermore, we discuss potential applications in radar cross-section analysis and antenna design, along with optimization approaches for enhancing computational efficiency through parallel processing and adaptive mesh refinement techniques.
