摘要：

详细推导了考虑边界电荷时RWG-MoM分析问题中涉及的阻抗矩阵计算公式，解决了阻抗矩阵计算中遇到的面积分奇异及线积分奇异问题，尤其是线积分奇异的处理，给出了巧妙的推导。通过仿真试验研究了边界电荷对电流分布及近场的影响，发现随着物体尺寸的减小边界电荷对电流分布及近场的影响逐渐明显。

Abstract:

With considering the influence of boundary charge， the formulations for calculating the impedance matrix using RWG-MoM are deduced in detail. The problems in calculating the impedance matrix， such as the problem of area integral and line integral singularity, are solved very well. Especially， the paper provides a piece of smart deducing to solve the line integral singularity. Through simulation， the impact of boundary charge on current and near-field distribution is studied， and it is found that the influence of boundary charge on current and near-field distribution increases with the size of objects decreasing.
