Since the multiple scattering should be considered, the scattering problem of many-cylinders is more complicated than single cylinder. By using scattering matrix method to solve the scattering problem of many-cylinders, first we have to express the incident fieldand scattered field by special function(for example, Bessel function and Hankel function)under cylindrical coordinate, then use the addition theorem of special function to get a linear system of equations to relate the incident field coefficients and scattered field coefficients. The incident and scattered field coefficients for every cylinder can be solved from the linear equations by matching electromagnetic boundary condition pointwisely.
单颗圆柱散射体的散射场解析解很早就被解出,而多个圆柱阵列的散射场问题因为涉及到入射光在圆柱与圆柱间的多重散射,故散射行为较单颗圆柱的散射复杂,因此圆柱阵列的多重散射问题需要利用加法定理来处理;散射矩阵法的主要精神即是先用圆柱座标下的特殊函数对平面波和圆柱散射体的内外域电磁场做无穷级数展开,再藉由特殊函数的加法定理将所有圆柱散射体的展开中心移到同一个展开中心,最后可以得到一组连结整个散射系统的入射电磁场系数及散射电磁场系数的线性方程组,将该组线性方程配合电磁场在散射体边界的连续条件,便可分别求出圆柱阵列中各个圆柱体的内部电磁场与外部散射场,再利用线性叠加原理即可求得整个圆柱系统的全域电磁场分布。

Under the cases of the linear interconnected systems with all its subsystems are one dimension, a theorem to judge the properties of single loop interactions has been given; the study also indicated that the properties of interactions cann't independent of the properties of subsystems in the multi-loop interaction conditions, and a all field root locus method has been proposed to decide the properties of interactions; a interaction stabilizable theorem has been given, and the efficacy of interactions with respect to the interconnected systems has been configured, Some primary results are reported which are induced by using a method of computer aided test to study block interactions, the stationary feedback efficacy of closed loop interactions have been discussed and a stability guess has been proposed.

In 1966, Ross solved the equation of symmetrical free vibration and got six matching solution, but he believed that it is impossible to find a solution which is useful in everywhere. In 1979, Goldenveizer printed a monography in which the uniformly valid representations of curved solution were published, but the representations of membrane solution were still not found. In 1988, Ruo-jing Zhang published the uniformly valid representation of six solutions for symmetrical free vibration and eight solutions for dissymmetrical free vibration for the first time.
但却碰到巨大困难。1966年,Ross给出了轴对称振动的6个匹配解,但却认为不可能求出全域一致有效解。1979年,Gol&denveizer等出版专著,给出了弯曲解的全域一致有效表达式,但仍然没有得到6个解中奇异薄膜解的全域一致有效表达式。1988年,张若京在其博士论文中第一次给出了轴对称6个解和非轴对称8个解的全部&全域一致有效表达式。
