Two-Dimensional Simple Perfect Electric Conductor Square Cylinder

In the MATLAB environment, automated meshing and coding can be implemented to simulate a two-dimensional simple perfect electric conductor square cylinder. The process typically involves creating a geometric model using MATLAB's PDE Toolbox or similar functions, followed by mesh generation using algorithms like Delaunay triangulation or advancing front method. Appropriate electromagnetic equations (such as Maxwell's equations with boundary conditions) are integrated and solved using numerical methods like finite element analysis (FEA) or method of moments (MoM). Key MATLAB functions involved may include pdegeom for geometry definition, initmesh for mesh generation, and assempde for equation assembly and solution. This approach enables detailed study of the square cylinder's characteristics and behavior through field value calculations at all nodal points. Multiple simulations with different parameters and conditions can be performed to comprehensively analyze the cylinder's performance. This methodology not only provides deep insights into electromagnetic field distribution patterns but also serves as valuable reference for related research fields, with potential applications in antenna design and electromagnetic compatibility studies.
