摘要:

为了避免出现截断边界及截断边界条件，提出了开放区域上的有限单元和无限大单元相结合的区域剖分方法，并给出了无限大单元上基函数的构造。数值结果表明，该方法具有很好的计算效率和计算精度。

Abstract:

In order to avoid the truncated boundary and then the absorbing boundary condition in solving electromagnetic field problems on unbounded regions, a partition technique based on finite elements associated with some infinite large elements is presented. Th
