【摘要】 本文推导了二维横各向异性媒质中电磁散射的差分方程，得到了９点的差分格式，并将不变性测试方程与该差分方程结合计算了具有任意横截面、非均匀、有耗和一般张量形式的二维横各向异性媒质柱的电磁散射。文中给出一些典型数值算例。数值结果表明，该方法在分析计算此类问题时是有效的且具有一定的优势。更多还原

【Abstract】 The difference equation with nine-point mesh of electromagnetic scattering from two-dimensional transversally anisotropic medium is derived in this paper.Themeasured equation of invariance and the difference equation are used to analyze electromagnetic scattering from transversally anisotropic medium cylinders with arbitrary section ,inhomogeneous,lossy and general electromagnetic parameters. Some results obtained for canonical anisotropic structures are given. The results show that this method is avail and have advantage in anlyzing and calculating this kind of problems.更多还原
