Electromagnetic imaging of the 2-D media based on Particle Swarm algorithm

Based on the Particle Swarm Optimization algorithm, the real parts of the 2-D homogeneous and the isotropic medium was reconstructed by the method of moment in the circle configuration, and the analysis was noise free and constrained. The result shows the reconstruction method was suitable in this circumstance. The study will provide the theoretical preparation, such as clinical diagnosis, remote sensing, nondestructive testing, and the theoretical guidance for the practical application of the electromagnetic imaging based on the electromagnetic wave theory.
