本文提出了一种快速、稳定的方法，用于由外边界上的超定数据重建层状介质中的电磁场。该过程可以例如用作反演算法中的数据预处理，以准确地对已知分层结构下的掩埋对象进行成像。我们的方法是基于连续使用所谓的近似传输条件，提供准确的重建层具有足够小的宽度。数值实验证明了该方法的可行性和有效性。
We propose a fast and stable method to reconstruct the electromagnetic field in layered media from overdetermined data on the outer boundary. This procedure can be used for instance as a data pre-processing in inversion algorithms to accurately image buried objects under known stratified structures. Our method is based on successive use of so-called approximate transmission conditions that provide accurate reconstructions for layers with sufficiently small width. The feasibility and efficiency of the proposed method are demonstrated by numerical experiments.
