摘　　要：本文利用椭圆柱坐标系中电磁场的纵向分量对空间函数电流矩—磁流矩向量的依赖关系,籍助于傅立叶变换,推导出一般金属椭圆波导中空间函数电流矩—磁流矩向量激励下的电磁场表达式。作为特例,作者计算了探针激励和小环激励两种方式下的激励场。In this article,the dependance of the longitudinal components of the EM field in the elliptical cylindrical coordinate on the electricmagnetic moment of spatial func- tion is presented.Furthermore,in aid of Fourier transformation technique,expressions for the EM field in the hollow elliptical waveguide excited by the space-functional electric-magnetic moment are given.To simplify our formular,the authors calculated the excited fields of probe and small electric current ring,respectively.
