| 摘 要： | 本文提出二维有耗介质柱局部逆散射的矩阵摄动理论。作为生物体的简单模型，当二维有耗介质柱内部结构发生局部变化时，其散射电磁场随之改变。本文根据矩阵摄动理论导出了变化的散射场与介电常数，电导率之间的简明关系，并得到逆问题的各阶摄动解。

| Abstract: | A matrix perturbation theory in the partial inverse scattering of two-dimensional lossy dielectric cylinder is presented. As a simple physical model of biological body, when the inside properties of a two-dimensional lossy dielectric cylinder partly vary, the scattering fields vary accordingly. In this paper, a simple relationship between the varied scattering fields and varied dielectrics is derived by using the matrix perturbation theory, and the perturbation solutions for inverse scattering are obtained. |
