Developing a Two-Dimensional Model Using FDTD

In this research, we employed the Finite-Difference Time-Domain (FDTD) method to construct a two-dimensional model. This computational model enables the visualization of target electromagnetic parameters through MATLAB-based implementation of diffraction tomography. The FDTD algorithm was programmed using MATLAB's matrix operations and iterative time-stepping capabilities, solving Maxwell's equations in the time domain through central difference approximations. The diffraction tomography implementation involves calculating wave propagation and scattering phenomena using discrete Fourier transforms and backpropagation algorithms. This technique provides enhanced clarity in observing target electromagnetic characteristics, with applications including object identification and imaging systems. The methodology offers significant value by generating comprehensive data that improves understanding of target features and properties through quantitative electromagnetic parameter analysis.
