摘要/Abstract

摘要：讨论了单站散射测量一般各向异性介质特征参数的正问题. 以接金属衬底的一般各向异性介质为例, 导出一般各向异性电磁材料复介电常数张量与其反射系数的关系式, 即对单站散射法测量的正问题进行理论分析, 然后用计算机进行模拟实验得到理想状态下的数据结果.最后提出实验测试系统设计和反演方法.

关键词： 单站散射, 各向异性, 复介电常数

Abstract: Complex values of permittivity of general anisotropic materials are manufactured by free- space single- receiver measurement method. The interaction of electromagnetic wave with anisotropic slab is of importance. An application of a grounded anisot ropic slab is included to formulate the expression of reflection coefficient and complex permittivity tensor. The values of reflection coefficient at different incidence angles are calculated and analyzed.

Key words: single- receiver measurement, anisotropic materials, complex permittivty tensor
