| 摘 要： | 考虑到利用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与计算，在平均边界条件的基础上给出了运动薄板电磁屏蔽边值问题求解的一种新的近似方法。经与精确边界条件下运动薄板电磁屏蔽边值问题的求解比较，发现该方法具有简便易行的优点，且在平均边界条件的有效应用范围内，可以足够准确地描述薄板两侧电磁场的分布情况

| Abstract: | Considering the complexity of solution for the problem of electromagnetic shielding by using precise boundary conditions, in order to simplify analysis and calculation of the problem on the basis of averaged boundary conditions, a new method of solution for the problem was presented on a moving large conducting plate. Compared with the solution obtained by using precise boundary conditions, the method is very simple and convenient, and in the applied limits of averaged boundary conditions, the distribution of electromagnetic fields in the free space outside the plate can be calculated with satisfactory accuracy. |
