The unimoment method presented by K. K. Mei in the midium of seventies is a hybrid numerical method, which combined the numerical technique with the analytical method. It provides a quite valid way for solving the electromagnetic scattering problems of complex objects and even buried complex objects. This paper gives detailed discussions about various computing techniques which are involved in practical problems. 单矩法 计算电磁场 混合数值方法 电磁散射 电磁辐射 the unirnoment method computing electromagnetic field the hybrid numerical method electromagnetic scattering eletromagnetic radiation O441.4 国家自然科学基金资助的课题 1993-06-01 2021-04-01 6
