通过对圆柱状结构中多层各向异性薄层吸波材料的电磁分析—柱体由金属柱芯和包围其外的多层各向同性介质材料组成,在各层之间和外表面涂覆各向异性薄层.考虑各薄层的输入阻抗,得出曲面结构内部及表面涂覆各向异性吸波材料散射场.根据级联矩阵和算法,在一定波段上进行RCS (Radar Cross Section)减缩,获令人满意的计算结果.

A curved structure consisting of a perfectly conducting circular cylinder coated by any number of coaxial thin anisotropic layers separated by isotropic regins of different materials is considered.Each thin anisotropic layer is represented by a sheet with an anisotropic jump impedance.The scattered field is determined via a chain-matrix algorithm.An optimization procedure is developed to minimize the radar cross section over an assigned frequency band by varying the geometric and electromagnetic parameters of the structure.Numerical results bases on this design procedure are presented and discussed.
