| 摘 要： | 考虑到采用电磁场精确边界条件处理电磁屏蔽问题的复杂性,为简化电磁屏蔽边值问题的分析及计算,本文利用局部平面波近似法,导出了运动薄导体壳上电磁场的平均边界条件,计算结果表明用该边界条件完全可以取代电磁场的精确边界条件.

| Abstract: | Considering the complexity of solution for the problem of electromagnetic shielding by using the precise boundary condition,in order to simplify analysis and calculation of the boundary-value problem of electromagnetic shielding,averaged boundary condition on a moving thin conducting shell is derived out by using approximation of locally plane wave.General vector expressions of the averaged boundary condition are given.Its applied limit is investigated by computer simulation and the result shows that the precise boundary condition of electromagnetic field can be replaced by the averaged boundary condition in this paper. |
