摘要

在这项工作中，我们描述了一种基于代价函数最小化的线性化逆方法，用于从多重散射区散射远场重建目标的介电常数。我们表明，在计算成本函数的梯度时考虑多重散射可以显著改善重建结果。

Inverse scattering in the multiple scattering regime using different gradient approximations

In this work we describe a linearized inverse method, based on the minimization of a cost functional, for reconstructing the permittivity of a target from scattered farfield in the multiple scattering regime. We show that accounting for multiple scattering in the calculation of the gradients of the cost functional ameliorates significantly the outcome of the reconstruction.
