摘要
本文运用迭代MEI过程对非均匀介质柱的多柱体散射进行了计算。该迭代过程充分运用了不变性特点，使MEI方程在各次迭代中反复使用，不仅减少了计算量也大大减少了所需的内存空间．对于不规则网格剖分下有限差分方程的建立，则采用了一种广义的测试系数的方法。文中将均匀介质多柱体散射作为非均匀情况之特例，与已有结果作了对比，获得良好的一致性。对非均匀介质柱的计算，也提供了算例。
Scattering by multiple inhomogeneous dielectric cylinder is analyzed in this paper by the iterative procedure based on the measured equation of invariance (MEI). This new iterative procedure makes full use of the invariance of MEI, which saves both the computing time and memory requirements dramatically. Finite difference equation for irregular meshes is obtained by a generalized measuring approach. As a special case of inhomogenuity, scattering by homogeneous dielectric multi-cylinders is calculated in comparison with those results available. Good agreements are achieved and validity is testified mutually. The case of inhomogenuity is also given as an example.
