论文摘要
本文涉及三维麦克斯韦方程的逆散射问题。反向散射问题旨在确定以固定频率从电磁近场数据中从电磁近距离数据中的双轴性周期散射器的形状。研究分解方法作为解决反问题的分析和数值工具。我们为分解方法提供了严格的理由，该方法可导致独特的确定和定期散射器的快速成像算法。提出了用于成像三维周期结构的数值示例，以检查该方法的效率。
This paper is concerned with the inverse scattering problem for the three-dimensional Maxwell's equations in bi-anisotropic periodic structures. The inverse scattering problem aims to determine the shape of bi-anisotropic periodic scatterers from electromagnetic near field data at a fixed frequency. The Factorization method is studied as an analytical and numerical tool for solving the inverse problem. We provide a rigorous justification of the Factorization method which results in the unique determination and a fast imaging algorithm for the periodic scatterer. Numerical examples for imaging three-dimensional periodic structures are presented to examine the efficiency of the method.
