Only based on good conductivity we can adjust integral structure of composites more and scheme out structural complex materials that are provided with higher shielding effectiveness.
The computational region of integral equation method is only the 2D conductivity abnormal section not the whole section, and the computational accuracy is greatly enhanced.
积分方程法的计算区域只是二维电导率异常剖面而不是整个剖面，可以大大提高计算精度。

The integral equations were computed by modified successive approximation method (MSAM). The method needs less computer memory requirements and is suitable for high-conductivity-contrast formation.
