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.
