逆Maxwell equations的可穿透矩形散射体的唯一确定

Unique determination of a penetrable scatterer of rectangular type for inverse Maxwell equations by a single incoming wave

Guanghui Hu, Long Li, Jun Zou

摘要:

本文研究二维电磁散射逆问题。我们证明,在TE极化的情况下,由一个单一的入射波激发的电远场图案的知识是足够的,以唯一地确定矩形类型的可穿透散射体的形状。作为一个副产品,唯一性也被确认为标量亥姆霍兹方程建模的逆传输问题的散射界面处的不连续法向导数。关键词:均匀性,逆介质散射,麦克斯韦方程组,单入射波,形状识别,直角

英文摘要:

This work is concerned with an inverse electromagnetic scattering problem in two dimensions. We prove that in the TE polarization case, the knowledge of the electric far-field pattern incited by a single incoming wave is sufficient to uniquely determine the shape of a penetrable scatterer of rectangular type. As a by-product, the uniqueness is also confirmed to inverse transmission problems modelled by scalar Helmholtz equations with discontinuous normal derivatives at the scattering interface. Keywords: Uniqueness, inverse medium scattering, Maxwell equations, one incoming wave, shape identification, right corners
