摘要
提出了柱状多层介质中的磁偶极子在任意介质层中的电磁场的递推算法,给出了磁偶极子产生的电磁波在柱状多层介质中的反射、透射系数和广义反射系数,从而得到了任意介质层中满足各层界面边界条件的电磁场解析表达式.
A recurrence method for getting electromagnetic field of magnetic dipote(MD) in cylindrical multi-layered medium is pointed out. Both reflection and transmission coefficient as well as generalized reflection coefficient in each layer are given, and then an analytic expression for electromagnetic field of MD, which satisfy boundary condition of each layer is got.
