摘要
基于粒子群算法,在环状构型下通过矩量法数值分析了二维均匀、各向同性连续介电常数实部,在无噪声、有先验约束情况下的重构。重构结果表明,该重构方法有较好的重构结果。该研究对基于电磁场理论的医学临床诊断乃至于对遥感、地球勘探、无伤探测等做了理论上的准备,也为生物体电磁波成像的实际应用提供了理论指导。
Based on the particle swarm optimization algorithm, the real parts of the 2-D homogeneous and the isotropic medium was numerically analyzed by the method of moment in the circle configuration, and the reconstruction was performed in the cases of no-noise and the prior constraint. The reconstruction results show the reconstruction method has a good effect. The study can 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.
