一种有效的数值吸收边界条件与MEI方法的比较

Comparison of an Efficient Numerical Boundary Condition with the MEI Method

本文给出了一种新的吸收边界条件，并与不变性测试方程法（ＭＥＩ）、矩量法在计算时间、存贮空间方面进行比较，结果表明运用这个条件在计算时间和存贮空间上都具有优点，是计算电大尺寸媒质柱体电磁散射特性的一种有效手段。

A novel numerical boundary condition is presented in the paper, which is compared with the method of measured equation of invariance(MEI) on computational time and memory requirement. It is demonstrated that the new boundary condition is of benefit both on the time and memory, therefore is an efficient method for computation of electrically large dimension objects.
