Permittivity reconstruction of mono-axial anisotropic medium

应用kDB系方法得到了分层各向异性介质反射系数的递推公式 .作为检验 ,kDB系方法与广义传播矩阵方法计算的反射系数结果符合很好 .应用遗传算法结合kDB系方法反演了各向异性均匀无耗介质板的电参数 ,比较了用同一频率不同入射角和用不同频率相同入射角反射系数的反演结果 ,讨论了反演各向异性介质参数的可行方法 .

Using the kDB system the reflection coefficient is computed when the layered anisotropic medium is illuminated by a plane electromagnetic wave. The computed results are in good agreement with those obtained by the generalized propagation matrix (GPM) method. We reconstruct the permittivity for a mono axial anisotropic medium utilizing the Genetic Algorithm. The applicable approach to reconstructing anisotropic permittivity is discussed.
