摘要: 考慮到利用精確邊界條件處理電磁屏蔽問題的復雜性,為簡化電磁屏蔽邊值問題的分析與計算,該文在平均邊界條件的基礎上給出了運動薄板電磁屏蔽邊值問題求解的一種新的近似方法。通過編程上機計算,得到了運動薄板近似傳輸系數(shù)的值,經(jīng)與精確邊界條件下運動薄板準確傳輸系數(shù)的值比較,發(fā)現(xiàn)兩種結(jié)果符合得很好。這表明本文中的方法不僅是簡便易行的,且可以足夠準確地描述薄板兩側(cè)電磁場的分布情況。

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 boundary-value problem of electromagnetic shielding, on the basis of averaged boundary conditions, a new method of solution for the boundary-value problem of the electromagnetic shielding on a moving thin conducting plate is presented. Compared with the solution obtained by using precise boundary conditions, the method presented in this paper 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. -
