The ratma can calculate the electromagnetic scattering of multiple cylinders , and can be used in remote sensing . in chapter 2 simply derivation of the ratma is given by the addition theorem , and the general t matrix of single cylinder is deduced . the worked out examples show th e effectiveness of the ratma in the analysis of the scattering field of single cylinder or multiple cylinders 由于递推t矩阵法不仅可以计算多个柱体或不同形状柱体的散射,而且可计算遥感上三维物体的散射,在第二章中,利用加法定理,简要地推导了递推t矩阵法,并用解析法推出了单个圆柱体在各种情况下的t矩阵(此t矩阵对导体和介质圆柱体的散射场计算都适用) ,最后计算了单个导体圆柱和两个不同大小介质圆柱体的散射场。
