Abstract

Electromagnetic methods are one of the most important tools for exploring the physical properties of scatterers. When the scattering object is polarizable, more information can be gained from electromagnetic measurements to determine the scatterer’s electrical properties. In this paper, an inversion scheme is introduced to extract induced polarization information from electromagnetic measurements. The inverse scattering problem is reformulated as an optimization problem that utilizes an efficient forward model solver to compute the scattered field. Furthermore, a simulated annealing approach is considered in the presented scheme, wherein different cooling schedules are evaluated to solve the inverse problem. The results of applying the proposed scheme to various case studies are reported.
用进化方法表征电磁数据中的诱导极化参数
电磁法是研究散射体物理性质的重要工具之一。当散射物体可极化时,可以从电磁测量中获得更多信息,以确定散射体的电学性质。本文介绍了一种从电磁测量数据中提取感应极化信息的反演方案。将逆散射问题重新表述为利用有效的正演模型求解器计算散射场的优化问题。此外,在该方案中考虑了模拟退火方法,其中评估了不同的冷却方案来解决逆问题。报告了将所建议的方案应用于各种案例研究的结果。
