An improved nonlinear approach to electromagnetic scattering

Abstract

To solve the difficult scattering problem, Born approximation, the most prevalent method, is used to linearize the expression of the problem. However, for electromagnetic (EM) scattering problem, especially in many practical cases, it has poor effect. On the base of works done by other geophysicists, the authors suggest a new approximation approach that greatly surpasses Born approximation. It is illustrated by an example of 2-D crosswell electromagnetic imaging.
